The final whistle blows and Chelsea are through to the quarter-finals with a relatively comfortable 2-0 victory.
David Luiz sends the free kick up and over the wall but there's not enough dip on it and Fabianski watches the ball over the bar.
Ramires almost finishes things off but his deflected, dipping effort skims the top of the net after flying just over the bar.
Cazorla tries to work an opening on the edge of the area but Cahill does well. Cazorla then pops up on the left and gets his shot away, though it's just off target.
Mata's free kick is cleared but Jenkinson can only play the ball out for a throw in on the Chelsea left.
Good play from Chelsea but Ba can't finish the move off. Vermaelen is then penalised for barging into Willian.
Ba wants a foul deep in the Arsenal half but the referee waves play on. Wilshere finds Rosicky but he loses out on the edge of the Arsenal area.
Monreal stands up a cross to the back post but Bertrand deals with it. Arsenal play on with Essien down on the deck but they can't take full advantage.
Ozil comes in menacingly from the left flank but his attempted pass through is gathered in by Schwarzer.
Koscielny steps in to stop a Willian break and gets Arsenal on the front foot but Ramsey's cross is too close to Schwarzer.
Cazorla does well to win it back for Arsenal but Jenkinson's run is denied. The move ends with Jack Wilshere shooting just over the top with his left foot.
Rosicky's shot is blocked by Bertrand inside the area before Essien is shown a yellow card for hauling down Koscielny.
Chelsea dominating in nearly every department now and that second goal has really taken the stuffing out of the home side.
Inches away from 3-0. Eto'o plays in Ramires who goes round the last man but his touch is heavy and forces him wide. The cross is played over and Koscielny just manages to scramble clear despite nearly putting the ball into his own net.
Ozil with a free kick into the Chelsea area and the ball appears to come off Cahill but a goal kick is given.
Giroud almost makes an immediate impact, but Schwarze denies him. Wilshere beat his man before Giroud nipped in with the effort on goal.
GOAL!!! (Juan Mata) A brilliant right-footed goal from the edge of the box from the Spain international. A throw on the left is flicked on by Eto'o, and then Willian, and finds it's way to Juan Mata, who rifles past Fabianski.
Ozil is found by Cazorla and tries to jink his way inside from the left but loses control of the ball when challenged by a pair of Chelsea defenders.
Ramsey allowed space on the edge of the box and gets his shot away but it's three feet wide of the post.
Eto'o bursts forward and Mata does well to maintain possession but Chelsea are forced back and the ball ends up all the way back with Schwarzer.
Bertrand deals with the threat of Miyaichi and sets Chelsea away. They build slowly through Mata and Eto'o before switching to the right but Essien tries a back flick which is badly judged.
Foul from Bendtner and free-kick taker Luiz attempts an ambitious 60 yard pass up to Eto'o but he can't latch onto the ball.
It's generally much better from Arsenal now but they haven't managed to create anything clear-cut yet.
Intricate passing from Arsenal on the edge of the Chelsea area but the Blues just do enough. Bendtner hardly covered himself in glory again, laying the ball off for Ramsey when perhaps he could have turned and tried to get a shot away.
Bendtner feels the wrath of the Arsenal faithful yet again as he gives it away just when the Gunners are building a head of steam.
Almost for Arsenal as Rosicky finds Ramsey whose shot is deflected and just trickles wide with Schwarzer wrong-footed.
Chelsea settling down into a nice rhythm but Cahill mishits a pass straight out for an Arsenal throw.
Mata dropping deep this time and finding Willian. He sets up Eto'o and the striker's shot is considerably better than his tame first-half effort but it's just wide of the Fabianski's left hand upright.
Both sides struggling to maintain possession in the early parts of the second half, with Eto'o not quite able to find Mata on the edge of the Arsenal box.
Rosicky beats a couple of men as he comes forward on the right but his pass forward isn't well directed and goes behind for a goal kick.
Arsenal start the second half and will need to be a lot brighter in order to trouble this strong Chelsea side.
Sky Bet are offering 11/2 for Arsenal to come back and win the game in 90 minutes, while Chelsea are 4/7 and the draw can still be backed at 5/2. It has to be said, that 4/7 looks pretty big at this rate.
The half time whistle blows and Chelsea lead 1-0. Arsenal are seriously missing Olivier Giroud, who is warming the bench.
Chelsea win the midfield battle again but Mikel's pass forward it over hit. The away side just looking to see out this half a goal to the good.
Arsenal come forward with purpose but get to the edge of Chelsea's area and give it away. Chelsea are working really hard to close the opposition down but Arsenal's front men really aren't offering enough right now.
Willian lays the ball back to Essien who tries a long range effort but his shot is another that spins well wide and ends up going out for a throw down by the corner flag. Not pretty.
Chelsea have clearly grown in confidence since the goal and plenty of groans are heard when Rosicky tries to force the issue and his pass goes through for a goal kick.
Good work from Willian to find Mata on the left wing but Ramsey gets back to make the challenge and play it out for a corner. The ball comes back out to the taker De Bruyne but he can't make anything of it.
Eto'o briefly looks threatening running at Monreal and cutting inside from the right wing but his shot is poor to say the least and eventually goes out for a throw in on the left.
Monreal gets a cross over from the left and Essien can only slice the clearance up over his own bar for an Arsenal corner.
Jenkinson the full-back in the action now but he can't quite wrap his leg around one to get the cross over.
Essien drives through a host of Arsenal midfielders before receiving the ball back from Eto'o and having a shot but it flies off an Arsenal defender and out for a throw.
Almost an equaliser for Arsenal and it's another full-back, Nacho Monreal, who comes close. He fires in a low left-foot shot but it's a couple of feet wide of the post. Mikel is booked for unsporting behaviour.
Arsenal try to hit back and Cazorla is at the heart of it. He comes in from the left and tries to thread a pass through for Miyiachi but there's just too much on it.
GOAL!!! (Cesar Azpilicueta) Eto'o heads the corner out again and sets up another attack. He bombs forward and the ball eventually bounces up into the air and Jenkinson tries to head back to his goalkeeper but doesn't get enough on it and it's the full-back Azpilicueta who nips in to tuck the ball away.
Cazorla turns on the style again with a nice pass out to the left before Rosicky wins a corner for the home side.
De Bruyne forces a throw in for Chelsea down by the corner flag but Cazorla tricks his way out of trouble and wins a free kick after Essien pulls him back.
Offside against Miyiachi who is found by Ramsey's lovely ball over the top. Replays show he was level.
Bendtner is awarded a free kick midway into the Chelsea half and Cazorla whips it over but Schwarzer comes out to claim an easy catch.
Rosicky puts Cahill under pressure and instigates an attack but Miyiachi's shot is blocked before De Bruyne does well to win a goal kick by playing the ball off Wilshere.
Arsenal break results in a corner after Miyaichi's cross takes a deflection. Cazorla's delivery is headed away by Eto'o at the front post.
Bendtner does well this time, laying it off for Ramsey but Chelsea win it back before Mata's attempted throughball is blocked.
Willian has a shot from the left edge of the penalty area and the ball is blocked behind for a corner but Arsenal deal with it.
Monreal gets down the left and finds a cross but Bendtner can only loop his header up into the air for Cech to come and collect.
Bendtner has a dig from a long way out after Rosicky finds the big man, but Cahill blocked the volleyed effort.
Mata and Eto'o taking turns dropping into the hole in front of the Arsenal back four but nobody has been able to get in behind just yet.
Eto'o does well in the middle of the park and sets Chelsea on their way, but Arsenal stand firm and force Chelsea all the way back into their own half.
Willian and Bertrand linking particularly well early on and it's the latter who tries to run onto a throughball, but he can't make anything of it.
The corner is headed away but Cazorla concedes another one with a needless heavy touch. The second corner is also dealt with by the Arsenal defence.
Mark Hall has been in touch: "As a gooner, I hate to say that I fear a Chelsea win tonight. Ozil was a great signing for the gunners but I always thought that we needed 3 or 4 signings to give us some depth. This will I fear show tonight. But come on you gooners do us proud ."
So it's the 10 changes for Chelsea, with just Gary Cahill keeping his place from the side that beat Man City at the weekend. The England man seems back in favour with Jose Mourinho now.
Willie Maher has this to offer: "Gonna be a close game tonight,im going 1-1. chelsea to introduce torres near the end and he will score the winner in extra time...cazorla and willian with the other goals! A red card in the game too, trust phil dowd to ruin it for us all."
Michael Dingle says: "We can't lose to Arsenal tonight. We have the better team by a mile. Eto'o to have a great game and get two, Mata to get the other. 3-1 Chelsea. COYB!"
Andy is quite specific with his prediction: "2-2 after extra time, Vermaelan sent off and Arsenal to win 4-3 on penalties, with Sideshow Bob missing the crucial kick....oh and Bendtner to miss a sitter from 2yards!"
Tom from Buckinghamshire: "Chelsea to win 3-2, Eto'o scoring 2 and mata. Ramsey and Cazorla to score."
Usama Khan says: "I predict 4-2 for chelsea with mata scoring at least one. Win or lose, Blue for life, Chelsea till I die!!"
Rowan Barnard: "I think it is time for the Arsenal youngsters to come of age, I'm going for 2-1 to the Gunners."
Great to read all your predictions. Of all the PRICE BOOSTS offered by Sky Bet, I could be tempted by the 80/1 for Santi Cazorla to score first and the game to finish in a 1‐1 draw.
Nick Aslett writes: "Much stronger Arsenal team than most Gooners expected. Bendtner to grab a surprise brace. Arsenal to win 4-3."
Mamun Ullah: "Expect Arsenal to win 3-1 because Arsenal are in top form and Chelsea not much in top form but they're alright as for now i can only see Arsenal winning this one. With the likes of Ramsey, Ozil and Cazorla, we can pull it off."
Kevin Dineen: "Though the sides are completely made over, it is interesting looking at who is on the bench for both teams. A good chance for the young guns to get in the game and prove their salt. Though Chelsea is feeling confident, I believe that the young Gunners will squeak out a victory today in an open and free flowing match. 2-1 to the good guys."
Alex Samuels from London: "Due to Chelsea's form the past week or so I can see a Chelsea win tonight with Eto'o and Mata scoring 2-1 Chelsea."
Phil from Hull predicts goals, emailing: "I can see an open game with feast of goals, picking a Chelsea 4-2 win with Eto'o to grab 2 and one from mata. Come on Chelsea."
Lloyd Francis writes: "Me again, fancy Chelsea to win this one in the battle of arguably the 2 form teams in the country. 2-1 chelsea. Mata & de bruyne. Cazorla or Ramsey for the gooners! Up the chelsea!"
Mo expects this one to go all the way, saying: "I think with the slightly weakened squads lined out by both managers, this will be a close encounter tonight, Arsenal to win on penalties! ;)"
Sky Bet make the away side 7/4 to win, with Arsenal 6/4 favourites and the draw priced up at 5/2. The firm also offer several PRICE BOOSTS, including Aaron Ramsey to score first at 12/1 and Samuel Etoo to score first at 8/1.
CHELSEA TEAM: Schwarzer, Azpilicueta, Cahill, David Luiz, Bertrand, Essien, Mikel, De Bruyne, Mata, Willian, Eto'o. Subs: Blackman, Ivanovic, Kalas, Ramires, Hazard, Torres, Ba.
