City miss the chance to go top of the table after being held at the Emirates. Arsenal responded superbly in the second half and took a deserved point, but it may not be enough to reignite their title challenge.
Negredo gets in behind Mertesacker, but the angle is always against him and his attempted lob goes well wide.
Cazorla's corner is headed up and Oxlade-Chamberlain attempts an overhead kick which flicks off Zabaleta and rolls back to Hart.
Great ball from Cazorla out to Gibbs. He attempts a cross to the far post but it is just too high for Sanogo.
Milner flights the ball into the box, but Szczesny takes control of the situation and races from his line to gather cleanly.
Rosicky is penalised for sliding in on Silva as the City man breaks forward. Decent position for the visitors here, some 40 yards out slightly on the left.
Oxlade-Chamberlain attempts to get past Milner down the right, but the City man tracks him well to prevent the cross.
City play it short and look to work their way into Arsenal's box, before Silva's pass goes through to Szczesny.
Sagna looks to break into the box, but Toure puts his body in the way and allows the ball to run out.
Desperate defending from Arsenal to keep out City. Silva's pass almost releases Nasri, before Toure is forced wide and Szczesny saves, with Dzeko's shot then deflected wide.
Silva stands his ground as Flamini leaps for the ball, leading to the Arsenal man taking a tumble to the turf, but he is quickly to his feet.
Cazorla flights a dangerous free-kick into the City box and Giroud gets to the ball first but can only guide his header wide of Joe Hart's goal.
Just under 20 minutes to go here. This will be a crucial period which could have a big say on the outcome of the title race.
Corner for City as Fernandinho plays in Milner, with Mertesacker blocking. Nasri's corner is headed away before Silva lashes a shot wide.
City are pressing again, with Fernandinho unleashing a long-range effort which Szczesny makes sure is going over with a finger-tip save.
Nasri attempts to lift a clever ball to Silva on the edge of the box, but his volleyed effort is blocked by the imposing frame of Mertesacker.
Now City go back on the attack and Navas earns a free-kick in a dangerous position near the goal-line after being brought down by Podolski.
VITAL SAVE FROM HART!!! Podolski gets in behind the City defence and is one-one-one with the keeper, who gets a crucial touch on the German's shot to put it behind for a corner.
There are some sloppy passes creeping into City's play now and the goal has given Arsenal a real impetus.
All of a sudden, City are on the back foot. Hart had to make an important save moments before Arsenal equalised, and then the City defence is static soon after the goal as a low cross by Sagna from the right bounces across their six-yard box and away to safety.
And Arsenal are back on terms! Flamini, who scored a late own goal against Swansea, converts from 12 yards out following Podolski's low cross into the area from the left flank.
Inches away from a second for City as Navas' drilled low cross is flicked out by Szcesny, with the ball striking Mertesacker and rolling narrowly wide of the post.
Long-range effort from Rosicky which is always going away from Hart's goal and is caught neatly by the ball-boy behind the goal.
Silva attempts a pass through the Arsenal defence to Nasri, but while the direction is right, the pass has far too much power.
City have dominated here at the Emirates. They've had more possession and created the better chances, but with only a single-goal lead, there's always a chance for Arsenal to get back into the game.
More possession play from City - they're not always hurting Arsenal when they have the ball, but with the lead, they don't need to.
Cazorla's corner is fisted away by Hart before Sagna's return is headed away by Fernandinho, with the flag going up for offside against the Gunners.
Excellent from Demichelis as he reads and then cuts out Podolski's cross from the left with Giroud lurking behind after a swift Arsenal break.
Kompany goes into the book - not for the excellent tackle on Giroud - but for an earlier offence as he body-checked Arteta previously in the move.
Solid challenge from Kompany on Giroud on the edge of the City box takes the ball, but leaves the Arsenal striker in a heap holding his foot.
Cazorla's attempted backheel to Sagna is cut out by Clichy. City's dominance is demonstrated in the stats, as they've had seven attempts on goal to Arsenal's one.
Toure goes into the book for pulling back Rosicky in the centre circle. Pretty cheap yellow card, to be honest.
Silva attempts to thread a pass through to Zabaleta. Arsenal intercept, but then gift the ball to Nasri, who drills in a low shot which Szczesny drops to his right to save.
After a spell of head tennis in the Arsenal box, Nasri clatters into Rosicky to give the Gunners a free-kick.
Fernandinho tries a shot from long range, which looks to be heading well wide anyway, but takes a deflection to give the visitors a corner.
Good cross from the right by Sagna, but Hart is alert to the danger and comes off his line to claim the high ball.
Nice move from Arsenal, with Cazorla, Rosicky, Podolski and Gibbs all involved, before the full-back's cross is shepherded back to Hart by Toure.
Giroud attempts a long-range Rooney-esque effort, but Hart controls with his feet, with the ball going wide of the target.
Flamini has the ball in the net from Podolski's cross, but the flag was correctly raised for offside as the ball bounces beyond Joe Hart.
Podolski loses the ball to Toure in the City half, with the midfielder immediately releasing Silva. The Spaniard races deep into Arsenal territory before finding Dzeko, whose shot hits the inside of Szczesny's post and falls perfectly for Silva to roll into an empty net from close range.
Predictable boos for Nasri every time he has the ball. The France midfielder hits a shot from outside the box which loops up and Szczesny pats down and gather at the second attempt.
Lovely touch from Giroud to pull down a deep cross into the box and then find Podolski, whose attempted cross is blocked by Zabaleta.
Navas is freed down the right again, but Gibbs does an excellent job of holding up the City winger and then poking the ball away.
Replays show that Dean got that spot on. Zabaleta was pulling out of the challenge and Rosicky fell over in anticipation of the contact.
Arsenal appeal for a penalty as Rosicky tumbles under the challenge of Zabaleta in the box after Cazorla's pass, but referee Mike Dean is not interested.
Flamini feeds the ball out to Sagna down the Arsenal right, who swings over a cross, but it's too long for everyone in the box.
Optimistic effort from Navas from the edge of the box, but he slashes the ball horribly high and wide of Szczesny's goal, much to the disgust of his team-mates and Pellegrini.
Now Zabaleta picks out Silva down the right, whose clever pass beats two men and finds Navas, but his ball into the box is hacked away by Arsenal.
The Navas-Zabaleta partnership is bearing fruit down the right flank, with the Argentina international holding off Giroud to swing over another cross which Mertesacker heads out.
Swift counter-attack from City is led by Nasri, who finds Silva. He gives the ball to Edin Dzeko, but the Bosnia striker dwells on it and Arsenal can clear.
Play switches to the other end and Arteta combines with Cazorla, forcing Demichelis to slide in and concede a corner, which comes to nothing.
City are immediately back on the attack and David Silva's pass sends Samir Nasri racing into the box. He pulls the ball back and Navas curls an effort wide of Szczesny's goal.
Navas and Zabaleta combine again and get beyond Gibbs. The full-back attempts a cut-back but Arsenal clear through Arteta.
City win possession and Jesus Navas attempts to feed the overlapping Pablo Zabaleta down the right flank, but Kieran Gibbs slides in.
Here we go - the players head out to a warm reception on a sunny evening in north London. Time for the pre-match handshakes and other formalities.
Just five minutes to kick-off now - thanks for all your pre-match contributions. Time for the serious business to get under way.
Dan Lewis from Arvagh, Co Cavan, says: "Providing we can keep it 0-0 for the first 20 minutes we might possibly have a good game on our hands." I'm guessing Dan's an Arsenal fan....
As mentioned earlier, Manchester City are unchanged from their midweek win against Manchester United. That's the first time they've gone with the same starting XI in the Premier League under Pellegrini, and the first time since January 2013.
If you want to have a flutter on today's game, then our friends over at Sky Bet have a host of markets available. City are evens favourites to take the three points, Arsenal are on offer at 5/2 and the draw is a 13/5 shot.
While we're on the subject of Giroud, here's a further interesting statistic. The French striker has made 21 appearances against Chelsea, Liverpool, Man City, Everton, Tottenham and Manchester United, but has managed just three goals in those games.
Opta stat No.3: Olivier Giroud has scored five goals in his last three games at the Emirates in all competitions.
Opta stat No.2: Manchester City have kept five consecutive clean sheets in the top-flight for the first time since 1915. They have never kept six in a row in the top flight.
Opta stat No.1: Arsenal have won just three of their last nine Premier League games (W3 D3 L3), this after a run of five successive victories.
Wenger tells Sky Sports that Oxlade-Chamberlain has been left out of the starting XI because of a slight muscle problem.
Chelsea's defeat today gives Arsenal a huge incentive, too. Win today and they move level on points with City and just three adrift of the table-topping Blues. This title race really is going down to the wire....
Paul in Lincoln says: "Twitchy bottom time for us Gooners... A very difficult game to win, but one we mustn't lose. I'd be happy to share a point here, but ecstatic with three. Well done Palace!"
Steve Murphy writes: "As a Gooner, I would love to see a win this evening but don't think we are strong enough to bounce back especially against someone as strong as City, fingers crossed though."
Meanwhile, City fan Jordan Green (any relation to Chris?) says: "With Chelsea losing 1-0 to Palace, if we win here, City will win the league, we can even afford to draw or lose against Liverpool and still win the league, come on City, I say 2-0 to City."
Chris Green is swiftly out of the blocks to have his say: "This should be a walk in the park for Pellegrini's side. Prediction: Arsenal 0-3 Man City, with Fernandinho and Nasri (2) scoring the goals."
Stunning result from Selhurst Park, and one which means that Manchester City can go top of the table tonight with victory - the first time they will have led the league since December 28.
Meanwhile, over in south London, there is a result of huge significance in the title race. FT: Crystal Palace 1 Chelsea 0.
Just one change for Arsenal from their midweek draw with Swansea, as Lukas Podolski is handed a spot in the starting XI after impressing off the bench on Tuesday. Alex Oxlade-Chamberlain is the man who misses out and has to be content with a role among the subs.
Arsenal: Szczesny, Sagna, Mertesacker, Vermaelen, Gibbs, Arteta, Rosicky, Flamini, Cazorla, Podolski, Giroud. Subs: Fabianski, Bellerin, Jenkinson, Kallstrom, Gnabry, Oxlade-Chamberlain, Sanogo.
Manchester City: Hart, Zabaleta, Kompany, Demichelis, Clichy, Fernandinho, Toure, Navas, Silva, Nasri, Dzeko. Subs: Pantilimon, Kolarov, Lescott, Milner, Javi Garcia, Negredo, Jovetic

If you want to have your say on this afternoon's contest, vent your feelings on Arsene Wenger's reign at Arsenal, or wax lyrical about Manchester City under Manuel Pellegrini, then why not drop me a line.
Kick-off is now just over an hour away and we will bring you the team news from Emirates Stadium just as soon as we have it.
The Etihad setback and the Stamford Bridge reverse were just two of the heavy defeats Wenger's side have suffered against a title rival this season, with a 5-1 drubbing at Anfield also throwing their title aspirations into serious doubt.
Manuel Pellegrini's men enjoyed a 6-3 triumph over the Gunners at the Etihad earlier in the season and go into today's clash on a high following their 3-0 derby triumph at Manchester United on Tuesday night.
Victory for City at the Emirates this afternoon would see them open up a six-point gap on Arsene Wenger's side, with the added benefit of two games in hand.
Arsenal, however, know that they are in the last-chance saloon in the wake of a humiliating 6-0 drubbing at the hands of Chelsea and their disappointing midweek home draw with Swansea.
With the games rapidly running out in the Premier League, this is a key fixture in the battle for the title with both clubs still harbouring hopes of silverware.
