Manchester City 3-1 Barcelona, Ludogorets 2-3 Arsenal: Champions League – as it happened

Well that is all we have time for on this Champions League live text. We'll be back with all the goals from Wednesday's games which include big games for Tottenham against Bayer Leverkusen and Leicester at FC Copenhagen. Until then, goodbye.

There is also a victory for Arsenal who have comeback from two goals down to beat Ludogorets and are into the last 16. Granit Xhaka, Olivier Giroud and Mesut Ozil did the damage for the visitors and along with PSG are done and dusted with this group.

Full time across Europe, including at the Etihad Stadium where Manchester City have thumped Barcelona. Pep Guardiola exacts revenge over his old employers as Kevin de Bruyne inspired a second half comeback, after Lionel Messi had put Barcelona ahead.

Goal: Basel 1-2 Paris Saint-Germain (Thomas Meunier)

Goal: Ludogorets 2-3 Arsenal (Mesut Ozil)

The comeback is completed by Arsenal and what a goal to seal what is sure to be a crucial win. Ozil collects Coquelin's pass, flicks the ball over Milan Borjan and tucks the ball into the corner. It's a delightful goal and Ludogorets must be sick of the sight of him.

Barcelona are going long in an effort to breach the two-goal deficit at the Etihad Stadium; that is desperation for you. City looking comfortable dare I say it.

Messi has been close to anonymous in this second period and his performance is summed up by a free-kick which is deflected behind without troubling Cabellero.

Goal: Basel 1-1 Paris Saint-Germain (Luca Zuffi)

Goal: Borussia Monchengladbach 1-1 Celtic (Moussa Dembele)

Goal: Manchester City 3-1 Barcelona (Ilkay Gundogan)

The La Liga champions are on the brink at the Etihad Stadium. City with a sweeping move downfield and when Aguero can't convert Navas' cross, Gundogan is on the mark to sweep home. Fifteen minutes left, but Barcelona look very much beaten.

Goal: PSV 1-2 Bayern Munich (Robert Lewandowski)

A word on Arsenal who are still being held by Ludogorets in Sofia. The Gunners have not really threatened in the second half, with the hosts doing much of the running as they search for a famous win.

This has been a fabulous game full of attacking football, certainly not one for either defence, and goodness knows what we might get in the last quarter. City are getting Jesus Navas however, somewhat curiously.

Against the bar! City living dangerously as Suarez nut-megs Stones and finds Gomes, whose left-footed effort smacks against the woodwork and to safety.

De Bruyne fires City into a second half lead.

Barcelona are rocking here and Manchester City are looking to land a hammer blow. Otamendi somehow doesn't connect with a Silva free-kick at the back post. The visitors haven't had a kick in this second half.

Goal: Manchester City 2-1 Barcelona (Kevin de Bruyne)

Sergio Busquets with a cynical foul on the edge of the penalty area and it gives City a well-placed free-kick. Kevin de Bruyne is over the ball and he curls it towards the back post and beyond Ter Stegen.

Chance for Raheem Sterling to put City ahead but his touch is too heavy and he finds the side-netting. Barcelona not got going at the start of their second period.

Second halves about to start around Europe.Worth noting that with Celtic losing in Monchengladbach, they are heading out of the Champions League. Victory for the Germans also piles pressure on City, who could do with completing their comeback against Barcelona in the second half.

Stunning half of football across Europe. Both Premier League clubs are being held, but having been behind they will be content with their work. Ilkay Gundogan's goal cancelled out Lionel Messi's strike, with Manchester City level with Barcelona, while Arsenal have come back from two-down to peg back Ludogorets.

Goal: Basel 0-1 Paris Saint-Germain (Blaise Matuidi)

Goal: Ludogorets 2-2 Arsenal (Olivier Giroud)

It's been a mad first half in Bulgaria but Arsenal are now level after trailing by two goals at one stage. It's a horror show for Milan Borjan, who comes for a Ramsey cross and is powerless to prevent Giroud heading into an empty net.

City almost go ahead before the break as Fernando shoots across goal somehow beyond the outstretched boot of Aguero.

Goal: Manchester City 1-1 Barcelona (Ilkay Gundogan)

Well, well, well. Barcelona guilty of overplaying, yes overplaying in their own half and City punish them ruthlessly. Sergi Roberto plays the ball across his own penalty area and Aguero intercepts, he finds Sterling whose cross is hammered home by Gundogan. Game on.

Barcelona threatening from almost every attack and City are fortunate to remain just one behind. First, Andre Gomes' strike is blocked six yards from goal by John Stones before Suarez heads wide from Messi's fine cutback. Marvelous attacking pressure this from the visitors, who are looking to kill this game in the first half.

Ludogorets celebrate taking a two-goal lead over Arsenal.

Goal: PSV 1-1 Bayern Munich (Robert Lewandowski)

David Silva wastes a chance to put a nervy Barcelona defence under some more pressure with an overhit free-kick. City need to make more of those chances.

Goal: Borussia Monchengladbach 1-0 Celtic (Lars Stindl)

Goal: Atletico Madrid 1-1 Rostov (Sardar Azmoun)

Goal: Atletico Madrid 1-0 Rostov (Antoine Griezmann)

Messi strokes Barca ahead following a flowing counter-attack.

Goal: Manchester City 0-1 Barcelona (Lionel Messi)

City carved open from their own corner and you-know-who has Barcelona ahead. Messi starts the move from his own half and with Neymar given yards of room to operate he picks out the onrushing Argentine who draws Cabellero and tucks into the corner.

Goal: Ludogorets 2-1 Arsenal (Granit Xhaka)

Lifeline for the Gunners. Ludogorets go to sleep from Ozil's cross and Xhake arrives on cue to fire into the corner low past Borjan.

The one flash point from the game at the Etihad Stadium; the yellow card for Raheem Sterling for diving.

Goal: Ludogorets 2-0 Arsenal (Claudiu Keșerü)

No need to adjust your screens. Arsenal trail by two in Bulgaria. Cafu runs Gibbs ragged on the right and crosses where an unmarked Keseru hammers into the net as defenders around him stopped and stared.

Goal: PSV 1-0 Bayern Munich (Santiago Arias)

Goal: Ludogorets 1-0 Arsenal (Jonathan Cafu)

The Bulgarians showed plenty of threat in the first game and they have been rewarded, albeit two weeks late. A free-kick from the right exposes Arsenal and Cafu comes in at the back post to tuck into the corner. His seventh goal in 10 games and the hosts are ahead.

Manchester City fans can't believe it as the home side are denied what looked initially like a stone-wall penalty. Aguero feeds Sterling, who draws the challenge from Umtiti and goes over. Referee Viktor Kassai is on the spot but he books the England winger. Replays are slightly inconclusive but the home support are fuming.

Chance for Arsenal in their first ever match in Bulgaria and it is Mesut Ozil again who goes through on goal but Borjan makes a low save.

Two former Barcelona and Spain midfielders embrace before kick-off.

City started with the intent of pressing Barcelona but the visitors are into their stride already, pinging the ball around without a care in the world. Luis Enrique's side are keen to press themselves, and they force Pablo Zabaleta into an early error.

Underway across the continent. Our focus on the two Premier League clubs in action tonight, but news of all the goals as they go in.

Teams in the tunnel across Europe, including at the Etihad Stadium where Manchester City's players look in awe of opponent Lionel Messi of Barcelona. Big night for Pep Guardiola.

Full time and it ends Besiktas 1-1 Napoli. A credible result for the hosts, who had led through Quaresma's penalty, before Marek Hamsik's screamer drew the Serie A side level. That keeps Napoli top of Group B but they miss the chance to secure qualification tonight.

Dries Mertens denied in stoppage time as Napoli seek a late winner. This one looks like being a draw in Turkey.

Says plenty about Arsene Wenger's intent in this competition that he has picked a full strength team to secure qualification - in a week which ends with the north London derby against Tottenham. Arsenal have Olivier Giroud leading the attack from the start for the first time this season and there is plenty of goals in this team.

Napoli bite straight back however and Marek Hamsik produces a virtuoso effort from fully 25 yards which bends into the far corner. Back level with eight minutes to go.

Speaking of which, we have a goal in the group match which is already underway and is into the closing stages. Besiktas have been under the cosh but Quaresma has stroked home the calmest of penalties with 12 minutes left to leave Napoli reeling.

As for teams which could be dumped out tonight. Dynamo Kiev, Celtic and PSV are all out if they lose and other results go their way.

Anything less than a point will ensure PSV can progress no further in the competition; should Celtic lose they Barcelona to beat Man City; while a loss to Dynamo coupled with a result in the other match will see them out.

We have only reached matchday four but already several teams can book their place in the last 16, while many can see their dream of reaching the knock-out stage end this week.

Arsenal, Paris Saint-Germain, Napoli, Barcelona and Atlético Madrid are the teams in question tonight. Wins for all five teams will be enough to see them through, apart from Napoli who need to prevail and hope Benfica are held by Dynamo Kiev.

There is a firework display currently being held outside of the Etihad Stadium ahead of kick-off, but Manchester City should guard against an explosive display from visitors Barcelona tonight who eased to a comfortable win at the Nou Camp two weeks ago. With a creaky defence, which is without Bacary Sagna and of course captain Vincent Kompany, you can't help but fear for City again tonight.

Back to Turkey where it is Napoli doing all the running against Besiktas in the battle to end the night top of Group B. It remains goalless after 55 minutes in a game officiated by the Premier League's own Mark Clattenburg. I will keep you updated as we build-up to the games at 7:45pm.

This is how Ludogorets will line-up against Arsenal

Borjan, Minev, Palomino, Moti, Natanael, Abel, Dyakov, Cafu, Marcelinho, Wanderson, Keseru.

Arsenal's team drops. Plenty of changes from the 6-0 win over Ludogorets at the Emirates - including a first start of the season for Olivier Giroud.

And now for Barcelona. One change from the team that finished the 4-0 drubbing a fortnight ago.

Ahead of schedule, Manchester City confirm their team to face Barcelona. Pablo Zabaleta starts at full-back as captain.

Alexis Sanchez in good spirits ahead of matchday four in the Champions League.

Teams should be with us within the next 20 minutes, but how can we expect both Premier League sides to line-up tonight?

Manchester City have an injury crisis at right-back so could recall Pablo Zabaleta while Sergio Aguero is likely to start after being dropped for the loss at the Nou Camp. Willy Caballero will deputise for the suspended Claudio Bravo.

For Arsenal, Theo Walcott, Santi Cazorla, Nacho Monreal and Hector Bellerin are all out through injury. Olivier Giroud and Aaron Ramsey are likely to start while David Ospina will come in for Petr Cech.

City's players have arrived at the Etihad Stadium ahead of kick-off.

You might be logging on thinking you have to wait over an hour and a half for the football to kick-off tonight, but you would be mistaken. In Turkey, Besiktas and Napoli have already kicked off their group clash. The Italian are level on points with the Turks at the half way stage in the group, and with Benfica in pursuit this is a key game as far as qualification is concerned. It's currently goalless at the Voadafone Arena but I shall keep you abreast of any developments.

Know the feeling when you turn up at an ex's for a house party, and he/she points and laughs at you with their friends during an evening of humiliation and torment. No? Just me and Pep Guardiola then.

Just less than a fortnight ago the two-time Champions League winner had his pants around his trousers back on his old stomping group as Barcelona - via the mercurial Lionel Messi - destroyed a Manchester City side who looked liked a fish out of water at the home of one of European football's giants.

Tonight, the Spaniard has the chance to avenge that defeat in the reverse group fixture at the Etihad Stadium. Barca have won all five of the pair's previous meetings, so what could possibly go wrong?

Elsewhere, there are seven other matches to get your teeth into including Arsenal's trip to Ludogorets where victory could secure them passage to the last 16 - a far cry from last season's close shave.
