Arsene Wenger has called this the 'biggest' game of the season — it also happens to be his 1000th in charge of Arsenal. Can he break Jose Mourinho's incredible Stamford Bridge record today?
The second half gets underway. SUBS - A couple of changes for Arsenal as Flamini and Jenkinson come in for Oxlade-Chamberlain and Koscielny. It's all about damage limitation for 10-man Arsenal.
48 minutes: 5-0? Almost! Torres breaks free and the rebound from the save falls to Luiz whose shot is saved again! Good double from Szczesny there.
51 minutes Yellow card: Rosicky puts in a clumsy late challenge on Azpilicueta from behind and gets booked. Azpilicueta is hobbling.
54 minutes: Arsenal trying to move forward now. Some positive signs for the bruised Gunners as they get some respite from Chelsea's attackers. They couldn't make anything of their first corner though.
60 minutes: Just wide! Something to cheer for Arsenal. After some slick passing, Cazorla receives the ball down the left, inside the box. He fires a low shot just wide of the far post.
62 minutes: Oscar nearly makes it 5-0! Szczesny the savios again. Torres runs down the right, inside the box, dribbles, cuts inside and lays it off to Oscar who tries the lob shot, Szczesny leaps and just gets his fingertips to help it over the crossbar. No corner given though!
63 minutes: Arteta lobs in a very good free kick but Flamini doesn't get the required power behind it.
66 minutes: GOAL!!! This was coming! Oscar makes it 5-0. Szczesny should have done better there. Oscar receives the ball inside the box an drives it low past Szczesny.
67 minutes: Substitution: Oscar is replaced by Mohamed Salah.
68 minutes: Szczesny almost makes another error! Luiz runs in and drills in a low shot towards the far corner. It bounces before Szczesny who fumbles but recovers well to make amends.
70 minutes: GOAL!!!! 6-0 Everyone wants to make merry here. Salah gets a goal on debut. Luiz provides a brilliant lofted ball down the left, Salah is set clear, he runs in and calmly places it past Szczesny's near post.
71 minutes Substitution: Luiz off and John Obi Mikel replaces him.
76 minutes: Sagna provides a good cross from left inside the box, Cazorla runs in to fetch the ball but Cahill clears with Cech running in.
80 minutes: Ivanovic whizzes down the right and provides a low cross but Szczesny intercepts to make the stop.
82 minutes: Salah gets his shooting wrong. It's Ivanociv again who's creating problems down the right. He cuts it to Salah outside the box but the debutant totally mis-hits it into the crowd.
84 minutes: Schurrle almost makes it 7-0. His crunches in a low drive from just outside the box and it flies inches wide of the far post.
90 minutes: Rosicky runs in from center and shoots it from 25 yards straight to Cech who palms it away. Giroud gets the ball on the rebound, outside the box, but he fluffs his shot way over the bar.
The FINAL WHISTLE goes and on a day when Arsene Wenger celebrated 1000 games in charge as Arsenal manager, Arsenal suffer a humiliating 6-0 defeat to Chelsea at Stamford Bridge. Chelsea sit pretty at top with 69 points. Liverpool are behind them with 62 points with two games in hand.
