21:40: Full time across Europe. Liverpool must beat Basel in their final group match in order to qualify for the last 16 after they relinquish a first half lead in the final moments against Ludogorets Razgrad. Their European campaign may not be lost but Brendan Rodgers' side are still waiting for that win.
Better news for Arsenal though who join Chelsea in the last 16 after beating the 2012 runners-up Borussia Dortmund. Impressive win for the under fire Gunners with Yaya sanogo and Alexis Sanchez getting the goal.
Well, that's all we have time for on this second Champions League matchday of the week. We'll have full coverage of the Premier League this weekend but until then, goodbye.
Red card: Erik Johansson (Malmo)
Goal: Malmo FF 0-2 Juventus (Carlos Tevez)
Goal: Anderlecht 2-0 Galatasaray (Chancel Mbemba)
21:32: Nightmare for Liverpool. Less than three minutes left and Dyakov beats Steven Gerrard to a bnear post header and Terziev heads in at the back post. Three added minutes left.
Goal: Ludogorets 2-2 Liverpool (Georgi Terziev)
Red card: Selçuk İnan (Galatasaray)
21:23: Sterling should put the game to bed in Sofia but is denied at point-blank range. Liverpool but no means comfortable here but are less than 10 minutes away from a crucial victory. Alberto Moreno on for the Reds.
21:21: Another injury for Arsenal as Yaya Sanogo limps off with a hamstring problem, and is replaced by Lukas Podolski. More injury trouble for Arsene Wenger to contend with.
Goal: Bayer Leverkusen 0-1 Monaco (Lucas Ocampos)
21:15: Liverpool anything but home and dry in Sofia and Marcelinho's shot is deflected behind for a corner. After the visitors survive the first wave of attack, Caicara sees his effort fly off target.
21:09: Not completely smooth sailing for Arsenal tonight as Mikel Arteta goes off with a calf injury and is replaced by Mathieu Flamini, who makes his 50th Champions League appearance.
Goal: Atletico Madrid 4-0 Olympiakos (Mario Manzukic)
21:06: Jordan Henderson's blushes spared as he blazes over with the goal at his mercy after Rickie Lambert's header is cleared off the line, as the referee had already blown his whistle - for no apparent reason.
Goal: Atletico Madrid 3-0 Olympiakos (Mario Manzukic)
21:04: Shinji Kagawa one of two changes for Dortmund as they attempt to get themselves back into this match but this will be a test of Arsenal, having thrown away a three-goal lead against Anderlecht.
21:00: Oh that is special. Alexis Sanchez doubles Arsenal's lead with a stunning curling effort beyond Weidenfeller from 25 yards. No guarantees, given what has previously occurred in the Champions League, but Arsenal look like heading for an all-important victory which could take them through.
Goal: Arsenal 2-0 Borussia Dortmund (Alexis Sanchez)
20:56: Alex Oxlade-Chamberlain is making his 100th Arsenal appearance tonight and he almost marks it with a superb goal. The midfielder takes the ball down and volleys on the run which leaves Weidenfeller rooted to the spot, but the ball bounces off the crossbar.
Goal: Malmo FF 0-1 Juventus (Fernando Llorente)
20:53: Meanwhile, Arsenal almost have a second as Sanchez runs through the middle of the Dortmund midfield, shaking off several challenges before forcing Weidenfeller into a fine low save.
20:50: Shot across the bows from Ludogorets early in the second half but Mignolet can watch the ball bounce wide. Liverpool will need to improve if they want to see this win through.
20:47: Under way in the second halfs of the games across Europe. No changes in our featured games in London or Sofia.
Goal: Anderlecht 1-0 Galatasaray (Chancel Mbemba)
20:33: Half time in both of the game involving the Premier League clubs and it's all going to plan. Liverpool did fall behind before Rickie Lambert and Jordan Henderson struck to give Brendan Rodgers a much-needed boost. Arsenal are also celebrating at the break with Yaya Sanogo's first goal for the club giving them a lead over a lacklustre Borussia Dortmund.
Goal: Atletico Madrid 2-0 Olympiakos (Mario Manzukic)
20:25: Even better news for Liverpool fans as their side take the lead in Sofia. Sterling gets in down the left and when he spots Henderson charging into the box he shapes a delicious cross into wards the back post and his England teammate is on hand to tuck beyond Stoyanov
Goal: Ludogorets Razgrad 1-2 Liverpool (Jordan Henderson)
Good news for Liverpool fans as already qualifier Real Madrid take the lead over Basel through Cristiano Ronaldo, who goes to within three goals of current Champions League record scorer Lionel Messi. Any result will keep Liverpool in the competition tonight, if that score stays the same.
Goal: FC Basel 0-1 Real Madrid (Cristiano Ronaldo)
20:18: Raheem Sterling with time and space in behind the Ludogorets midfield, but he lashes his effort from 25 yards high over the bar. Liverpool not got going since they drew level.
20:11: More problems for Mignolet as Liverpool's hapless stopper flaps at a free-kick from the right, gets nowhere near it but is fortunate to see the ball fly through as the visitors survive.
20:08: Mkhitaryan is the latest Dortmund player to go close to levelling but he only hooks the ball over the bar. Arsenal's possession is currently infrequent, with Groskruetz and Gundogan breaking up attack in their infancy.
20:05: Some gremlins in the system at IBT towers so apologies for the lack of updates. Liverpool might be level in Sofia but they are no more secure at the back and Ludogorets are the dominant force. Dortmund are also dictating at the Emirates Stadium and they're almost level when Piszczek low, fizzing cross is just beyond the reach at the back post of Immobile.
Goal: Atletico Madrid 1-0 Olympiakos (Raul Garcia)
19:55: Liverpool behind for just four minutes. Allen's floated ball forward is headed on by Lambert and when Motti hesitates Lambert heads home the loose ball and scores his first ever European goal. Crucial for the Reds.
Goal: Ludogorets Razgrad 1-1 Liverpool (Rickie Lambert)
19:52: Early drama involving both English clubs. Arsenal take the lead after just two minutes as Sanogo shows superb control to tee up Cazorla, who returns the ball to the French youngster who despite appearing to be in an offside position strokes underneath Roman Weidenfeller to net his first professional Gunners goal.
However, for Liverpool it's a different story as Bulgarian side Ludogorets take a shock third minute lead. Marcelinho's shot is spilled horribly by Mignolet and Dani Abalo, who scored in the first game at Anfield, crashing home the rebound.
Goal: Ludogorets Razgrad 1-0 Liverpool (Dani Abalo)
Goal: Arsenal 1-0 Borussia Dortmund (Yaya Sanogo)
19:45: Players are out and we're under way across Europe. In our earlier game, Zenit beat Benfica 1-0, to knock the Portuguese club out of the competition.
19:42: So if you're new to IBT's Champions League coverage then this is how things work. Our focus will be on the Premier League duo, Arsenal and Liverpool with updates as the game progress while from across Europe we'll have updates as all the goal go in in each of the four groups. You need not go anywhere tonight.
19:40: Time to focus on Arsenal-Borussia Dortmund, which sees the top two clubs in Group D collide at the Emirates Stadium. There might not be much on the line, but the Gunners will be looking to react after the loss to Manchester United while Dortmund, though they have qualified for the knock-out phase of the Champions League, will want to show further signs of improvement having lost seven of their 12 league games this season, a run which sees them third from bottom of the Bundesliga.
19:30: The IBT mathematicians have had their calculators out all day crunching the numbers ahead of tonight's tie and have all the permutations sorted ahead of tonight's action. While Arsenal need just a win to qualify, Liverpool's task is far more complicated.
A win for Liverpool tonight and victory in a fortnight against Basel will see The Reds into the last 16, provided Real Madrid beat the Swiss champions tonight. A victory by two goals will be enough for Liverpool over Basel if they do indeed beat Real.
A draw or a defeat means victory for Basel tonight will see Liverpool crash out. Liverpool would then have to beat Basel, hope Real beat Ludogorets on matchday six and then pray that fortune is on their side when it comes down to goal difference between the three teams.
19:22: Some interesting team news to report from The Emirates and Sofia. Arsenal make three changes from the defeat to Manchester United, all three of which are enforced by injury. Wojciech Szczesny, Jack Wilshere and Danny Welbeck are all out, with Damian Martinez, Mikel Arteta and Yaya Sanog coming in.
Liverpool have made three changes as well with the highest profile returnee being Jordan Henderson, who comes in after injury. Kolo Toure and Lucas Leiva are also back in for Brendan Rodgers with Rickie Lambert starting in attack again after scoring his first goal for the club in the defeat to Crystal Palace.
Arsenal v Borussia Dortmund
Arsenal: Martinez, Chambers, Mertesacker, Monreal, Gibbs, Arteta, Ramsey, Oxlade-Chamberlain, Alexis, Cazorla, Sanogo
Borussia Dortmund: Weidenfeller, Piszczek, Subotic, Ginter, Schmelzer, Gündogan, Bender, Großkreutz, Aubameyang, Mkhitaryan, Immobile
Ludogorets Razgrad v Liverpool
Ludogorets Razgrad: Stoyanov; Júnior Caiçara, Moţi, Terziev, Minev Y.; Dyakov, Fábio Espinho; Misidjan, Marcelinho, Alexandrov; Dani Abalo
Liverpool: Mignolet, Manquillo, Skrtel, Toure, Johnson, Lucas, Allen, Henderson, Gerrard, Sterling, Lambert.
19:00: After Chelsea and Manchester City provided double delight for the Premier League on Tuesday, can two of the league's most scrutinised clubs come away with a moral boosting win tonight? Arsenal know a point tonight against Borussia Dortmund will all but secure their place in the last 16, but victory will not only guarantee progress but keep them in with a slim chance of overhauling the German side and finishing top of Group D.
For Liverpool, while Brendan Rodgers' side - baring a bizarre series of results - are likely to be in contention to reach the knock-out phase regardless of their result against European minnows Ludogorets Razgrad tonight, they are in desperate need of a confidence-boosting win after a run of three straight defeats. Rodgers has come under pressure amid some uncertain performances this season and while he will be hoping Real Madrid overcome Basel in Switzerland, he needs some favours from his own players if he is to cement his position at Anfield.
