Hector Bellerin rescues a point for Arsenal as Alvaro Morata rues big misses for Chelsea

Phew. What a thriller. Chelsea stay in third place behind Manchester United and Arsenal remain sixth after an enthralling contest in north London. On a night where Alvaro Morata forgot how to finish, Marcos Alonso and Hector Bellerin have shown him how it's done.

Full-time: Arsenal 2-2 Chelsea

Chelsea denied a winner! Alvaro Morata misses another clear cut chance, breaking between the Arsenal defence and moving one-on-one with Courtois. His attempt on goal is awful, dinking it straight into Cech's chest but the ball bounces back out to Zappacosta who hammers the rebound on goal. It looks destined for the top corner but it comes back off the underside of the bar!

Bellerin equalises! A cross is only partially cleared by Chelsea and the loose ball bounces to the Spaniard inside the box, who connects with a flawless half-volley, guiding it past Christensen and past Courtois in goal. Wonderful equaliser.

Goal! Arsenal 2-2 Chelsea (Hector Bellerin, 90+1)

Bellerin stays onside as he is fed down the right channel and lifts a ball across the face of goal but no one can get on the end of it!

Sanchez sees his effort from inside the six yard box blocked and Wilshere's attempt to cross the ball over to the back post is momentarily cleared. Arsenal come again though...

Four minutes of time added on at the Emirates.

Alonso has done it again, Chelsea are heading towards three points and second place as things stand.

Theo Walcott is on for Chambers before the corner comes in but Chelsea deal with it. Mustafi connects with a superb volley as the ball comes back in but Cahill makes a terrific block to keep it away from goal.

Mustafi hoofs a ball down the inside right for Welbeck to run onto in acres of space. Ozil and Sanchez are waiting in the middle but the former Manchester United forward can#'t find them, winning a corner.

Arsenal have five minutes to rescue something here.

Chelsea have the lead! Maitland-Niles has been superb tonight but on this occasion he loses out to Zappacosta, with the Italian turning inside the young full-back before pinging an inviting ball across goal from the right. There are three Arsenal players inside the six yard box but Alonso makes a terrific run in between the lot of him to drill home from close range.

Here's another Chelsea change and it is Hazard coming off. The Belgian doesn't look like he is carrying a knock as Willian comes onto replace him.

Bellerin does superbly well down the right to burst past his man and lift a cross into Welbeck but Zappacosta does well to usher the ball away.

And a change for Arsenal; Lacazette comes off to be replaced by Danny Welbeck.

Hazard frees Morata with an absurd piece of skill, allowing the Spaniard to race down the inside left channel. Hazard has raced into the box for the return but Cech gets to it first.

15 minutes left in this pulsating clash in north London.

But he was brought crashing back down to earth moments later when Chelsea were awarded the penalty.

Take off for Jack Wilshere....

Another change for Chelsea: Danny Drinkwater is on for Fabregas.

Arsenal are caught out at the back again and Fabregas can pass a ball through the middle for Morata to race onto. Mustafi is doing his best to keep up with him and manages to put the striker under just enough pressure to force him to fire wide.

Hazard steps up... and slots it past Cech! For the second time in four days, Arsenal lose a lead to a penalty - this one looked a bit soft, too. Arsene Wenger will be cheery post-match...

Goal! Arsenal 1-1 Chelsea (Eden Hazard, 66)

Hazard twists and turns inside the box, looking to lift the ball into the six yard area. For a moment it breaks loose, inviting Bellerin to challenge for the ball but he is judged to have fouled the Belgian. Penalty!

PENALTY - Chelsea

Arsenal with an immediate chance to make it two! Lacazette is slowed down by his marker inside the box but still manages to get the shot off, drawing a save out of Courtois.

Wilshere puts Arsenal ahead! What a moment for the England international. Ozil looks inside to Holding whose pass takes a slight nick off Bakayoko, allowing the ball to break to Wilshere inside the box. The angle is tight, but he lashes an unstoppable strike on the bounce into the roof of the net, leaving Courtois with no chance.

Goal! Arsenal 1-0 Chelsea (Jack Wilshere, 62)

Arsenal pass up another chance! Ozil draws Azpilicueta in to take him on but instead plays a rapid one-two with Lacazette to creep into the six yard area. He tries to pass across goal rather than shoot and Chelsea manage to clear.

Amid a string of corners for Arsenal, Alonso goes down in the box and the free kick is given Arsenal's way.

Bellerin almost dances his way through down the right with a little help from Ozil but Christensen gets a foot across just in time to force the corner.

Mustafi comes out and hauls Hazard to the ground, cynical as you like. Hilariously, he feels the need to protest the decision.

Here's Chelsea's first change of the evening, Davide Zappacosta is on for Moses.

Arsenal are furious they haven't got a free kick here. Lacazette touches it down on the edge of the box for Wilshere who goes down under the challenge from Christensen, but was there contact? If there was, it was the Arsenal midfielder who initiated, dropping his leg into the Chelsea defender to ensure there was contact. Wilshere is already booked, that could have been another for simulation...

In the aftermath of all that, Rob Holding went into the book for a foul on Fabregas.

Courtois to the rescue again! Brilliant football from Ozil and Sanchez who combine before finding Lacazette. He goes for the return pass, but the ball deflects off Cahill's ankles and breaks to him right in front of goal with only Cech to beat. Lacazette goes for power over finesse, hammering a shot on goal but Courtois is out to make himself big and make the block.

Up the other end, Maitland-Niles swings in a beaut of a cross from the left having brought the ball back in on his right. His cross beats Cahill, but Lacazette can't quite direct his header on target.

Cech denies Hazard! It's a brilliant piece of skill from Morata in the centre circle, letting the ball roll up his chest and flicking it onto Fabregas who frees Hazard with an excellent through ball. The Belgian goes low, but Cech gets down in time, denying him with a fine save.

Morata brilliantly spins past Chambers who clatters through the Spaniard, somehow avoiding a yellow card.

And Chelsea get us back underway for the second half.

Half-time: Arsenal 0-0 Chelsea

What a chance for Chelsea to take the lead just before half-time! Kante wins the ball back from Ozil on the half-way line with a brilliant challenge and prods it forward to Hazard who races at the Arsenal backline. He cuts across goal, taking two players with him before backheeling into the path of Fabregas, who has a clear sight on goal thanks to his teammate's brilliance. Fabregas takes on the first time shot, but lifts a poor effort over the bar. That should be that for the first half.

Fabregas now picks up a yellow card; the Spaniard gets his toes to the ball to prod it away but takes down Wilshere on the follow through. Bit harsh, that one.

We are into the final five minutes of the first-half. Former Barcelona teammates Cesc Fabregas and Alexis Sanchez share a hug.

It's Alonso who takes it with that wand of a left foot but there is too much pace on his effort and he whips it over the wall and over the bar.

A Marcos Alonso special from this angle? It's set up for a left footer.

Chelsea have a free kick right on the edge of the box and Arsenal are furious. After Bellerin fails to properly clear the ball, Morata lays it off to Bakayoko and Xhaka comes crashing through the side of him. It was clumsy and really, Arsenal can have no complaints.

Ozil lofts a dangerous ball into Sanchez, who has continued into the box after laying the ball at the feet of the German, but Cahill follows him all the way and does well to clear the danger.

Fabregas lofts in a wonderful diagonal pass for Bakayoko, who has crept in unmarked behind the Arsenal backline. The Frenchman can't pluck the ball out of the air however and it rolls out of play.

Ozil is being given a bit too much space this evening; he is getting plenty of time on the ball and Chelsea aren't alive to his threat at the moment. He slides another clever ball into Wilshere on the edge of the box but Fabregas gets back in time to nick the ball away and clear the danger.

Wilshere picks up the first yellow card of the game. Bellerin knocks the ball loose with a neat challenge on Hazard but his teammate's is less clean, taking out his old teammate Fabregas.

Bakayoko suddenly pops up in the box, fed through by Fabregas. Under pressure from Maitland-Niles he hits a shot straight at Cech who palms it over the bar.

Another good save from Courtois! Bakayoko leaves Ozil in space and the German can find Lacazette in the box. The striker spins Cahill brilliantly to move the ball onto his right foot and look for the bottom corner but the Chelsea goalkeeper is equal to it.

It's been a tough opening 20 minutes at the Emirates; both sides will feel they could be ahead.

Another look at that penalty appeal from Maitland-Niles; the Gunners youngsters drifted past Moses down the left before cutting inside the box with Christensen ahead of him but did appear to just trip up over his own feet.

How did that not end up in the back of the net! Maitland-Niles wants a penalty after going down inside the box but Anthony Taylor waves play on with Arsenal swiftly winning the ball back in the box. Maitland-Niles and Sanchez combine brilliantly before the latter hammers a shot on goal that Courtois gets a hand to, pushes it onto the post. It bounces across goal and comes off the inside of the other post, but won't roll over the line! Chelsea survive.

Morata is almost in again, scampering in at the near post to try and get onto the end of Moses' pass. He bursts ahead of his marker but Cech just about gets their first. That Arsenal back three isn't looking to sturdy at the moment.

Huge miss from Morata! Chambers loses his concentration completely as a ball comes over the ball and the Spaniard is free to run onto the loose ball with only Cech to beat. One-on-one, he opens up his body and tries to slide it past the goalkeeper but misses the target, sending it wide of the far post!

Moments after an Arsenal move breaks down in the final third, Chelsea bounce forward on the counter with Morata dinking a ball over for Hazard to run onto with Bellerin caught the wrong side. He shoots across goal, settling for the corner but it is an easy catch for Cech.

Or not. Chelsea play it short and after a brief flurry of passes, a loose one finds its way through for Cech.

Morata is now caught by a late challenge from Mustafi and Chelsea now might have the chance to load the Arsenal box.

Chelsea clear and Arsenal have the ball back deep in their own half.

Sanchez takes it and a big deflection leaves Courtois stranded. Lucky for him, the deflection takes it the wrong side of the post and out for a corner.

Ozil and Sanchez stand over this...

Ozil finds a pocket of space and threads a fine ball upfield to Sanchez. He shifts it inside to Lacazette who waits for the challenge from Kante and wins a free kick for his side from about 25 yards out.

Calum Chambers is called into action for the first time, leaping into intercept Alonso. Referee Anthony Taylor awards the free kick to Chelsea however and with Chambers turning his back to the ball, Chelsea play it quickly, trying to find Hazard in the box. He settles for a corner, which Arsenal deal with comfortably enough.

And Arsenal get us underway at the Emirates.

Five minute warning; here's one last look at those teams before kick-off.

Arsenal team to face Chelsea: Cech, Chambers, Mustafi, Holding, Bllerin, Xhaka, Wilshere, Maitland-Niles, Ozil, Sanchez, Lacazette

Subs: Ospina, Mertesacker, Coquelin, Elneny, Walcott, Iwobi, Welbeck

Chelsea team to face Arsenal: Courtois, Azpilicueta, Christensen, Cahill, Moses, Kante, Bakayoko, Fabregas, Alonso, Hazard, Morata

Subs: Caballero, Rudiger, Zappacosta, Drinkwater, Willian, Pedro, Batshuayi

Speaking to Sky Sports, Arsene Wenger says he "thinks" Mesut Ozil is 100%. The Germany international returned to training on Tuesday afternoon before passing a fitness test.

Calum Chambers appears to have won his manager's faith again.

Arsenal picked up a valuable point away to Chelsea at Stamford Bridge back in September and comfortably beat Tottenham Hotspur at the Emirates in November, but their record against top four rivals this season has room for improvement.

That home defeat to Manchester United in December and a draw at home to Liverpool just before Christmas are responsible for the current gap between them and the top four.

Should Arsenal fans be concerned by that backline tonight? Callum Chambers and Rob Holding, 22, start a league match for the first time since the first day of last season, a 4-3 defeat to Liverpool.

With Laurent Koscielny and Nacho Monreal unavailable however, Arsene Wenger has little other alternative. His only other available centre-half is Per Mertesacker, and you would fear for the BFG should Eden Hazard get at him...

As mentioned, this is the first of three meetings between these two sides over the next three weeks. The next instalment in the trilogy takes place at Stamford Bridge in the first leg of the Carabao Cup semi-final on 10 Wednesday before we head back to the Emirates on 24 January for the return leg.

Antonio Conte makes four changes to the side that put Stoke City to the sword on Saturday. As mentioned, Eden Hazard and Cesc Fabregas come back in along with the rested Tiemoue Bakayoko. Andreas Christensen also reclaims his spot in the heart of defence. Willian, Pedro, Danny Drinkwater and Antonio Rudiger are those to drop to the bench as the Italian boss keeps his rotation policy in full flow.

Three changes for the Gunners tonight. As Arsene Wenger tends to do against sides that do the same, he has named three at the back tonight with Rob Holding coming in for Laurent Koscielny, who misses out completely tonight. So does Sead Kolasinac, another injury victim after that bruising New Year's Eve encounter with West Brom, so Ainsley Maitland-Niles comes into replace him on the left.

Jack Wilshere and Granit Xhaka retain their places in midfield but Alex Iwobi drops to the bench with Mesut Ozil passed fit to return to the starting XI after a recent knee problem.

Chelsea team to face Arsenal: Courtois, Azpilicueta, Christensen, Cahill, Moses, Kante, Bakayoko, Fabregas, Alonso, Hazard, Morata

Subs: Caballero, Rudiger, Zappacosta, Drinkwater, Willian, Pedro, Batshuayi

BREAKING: Cesc Fabregas and Eden Hazard return to the Chelsea starting XI.

Arsenal team to face Chelsea: Cech, Chambers, Mustafi, Holding, Bllerin, Xhaka, Wilshere, Maitland-Niles, Ozil, Sanchez, Lacazette

Subs: Ospina, Mertesacker, Coquelin, Elneny, Walcott, Iwobi, Welbeck

BREAKING: Mesut Ozil passed fit to start against Arsenal.

Predicted Chelsea XI

We expect Cesc Fabregas and Eden Hazard to come right back into the starting XI tonight with the Belgium maestro to play off Alvaro Morata - who was taken off early in that thrashing of Stoke City to have him prepared for tonight.

Predicted Arsenal XI

Arsene Wenger likes to jump between three and four at the back but more often than not, he will opt for the former if that is how the opposition are lining up too. With Laurent Koscielny and Nacho Monreal out however, that means the Gunners boss will have no choice but to call upon Per Mertesacker if he does opt for that system tonight.

Ainsley Maitland-Niles has proven to be an extremely reliable option on the left over the month; Sead Kolasinac's absence should usher him back in.

Eden Hazard and Cesc Fabregas both started on the bench against Stoke City on Saturday; not that they were missed, with the Blues taking a three goal lead inside half an hour. Conte has so far found harmony in his rotation policy over the busy period and suggests it will be in place again tonight.

It is very important in my plan to involve all my players. We are doing a really good job in this situation because we are making many rotations but at the same time our results are positive.

"My target is to have all my players in the peak of their form, especially as there is now the second part of the season and this is the very important part because you are able to reach your target or not reach you target.

Chelsea have no such problems; Antonio Conte has no fresh injury woes with David Luiz and Charly Musonda his only absentees with both expected to return this Sunday against Norwich City in the FA Cup.

Wenger on Koscielny and Kolasinac

[On Koscielny] yesterday the medical staff were pessimistic. He is 30% available, 70% not available. Kolasinac is out completely for at least two weeks.

"We dedicate our time to recovery. We work a little but today for preparing for tomorrow's game. Basically it is 80% recovery, 20% training. We have a squad equipped to deal with that, we have proved that in the Europa League, but we cannot lose any more players now because we are a bit a short.

Arsenal's injury list is a pretty beefy one, even if Koscielny and Ozil have managed to recover in time. Aaron Ramsey remains sidelined with a hamstring injury while Nacho Monreal is still recovering from an ankle injury suffered in the clash against Liverpool before Christmas.

Olivier Giroud, meanwhile, sustained a hamstring issue in the Carabao Cup quarter-final victory over West Ham United, while Santi Cazorla remains a long-term absentee.

Arsene Wenger will certainly be the more stressed manager ahead of kick-off having seen his squad shrink shorter and shorter over the last two weeks. If surrendering a win over West Brom on New Year's Eve wasn't frustrating enough, the Gunners also lost two key defenders in Laurent Koscielny and Sead Kolasinac to injury.

Wenger rated Koscielny's chances of featuring tonight at around 30%. Kolasinac? No chance, he sidelined for the next two weeks with a knee issue.

Mesut Ozil sat out of that draw at the Hawthorns due to a minor knee problem. A late fitness test will decide whether the German plays tonight.

These two will be sick of the sight of each other by the time the month is out. Arsenal and Chelsea were drawn against each other in the Carabao Cup semi-finals last month and will meet in a two-legged affair to be played over the next three weeks.

Before that, there is the small matter of their Premier League showdown. Arsenal are just about keeping pace in the race for a Champions League spot but are six points adrift of fourth place Liverpool ahead of kick-off. Another defeat to a top four rival – at home none the less – will be damaging to those ambitions even at this stage.

Both managers have understandably bemoaned the fixture list that has left their respective sides a little ragged over the festive period. Tonight is the last fixture before relative normality returns – let's hope they both have enough left in the tank.

All your team news is on the way.
