And that's it! For the first time in 14 attempts Arsene Wenger has a win over Jose Mourinho. Cue Chelsea fans dismissing today's game as a meaningless pre-season friendly and their Arsenal counterparts claiming a powerful psychological victory. Well deserved from the Gunners today, anyway.
FULL TIME: Arsenal 1-0 Chelsea
Courtois denies Arsenal again! Brilliant interplay from Arsenal again with Cazorla threading a wonderful pass through to find Gibbs' intelligent run. He tries to slot past the big Belgian but Arsenal are again denied a second. It's unlikely to matter though....
Four minutes of time added on just as Arsenal win a free kick inside their own box after another half chance for Chelsea.
Matic is fouled after some neat footwork and all of a sudden it kicks off a bit with players from both sides squaring up. Anthony Taylor calms things down and Fabregas is able to swing the free kick into the box only for Ivanovic to head wide. Minutes of the contest left.
Arsenal so close to a second! Living on the counter, Cazorla is left on his own just inside the box after Giroud's brilliant run took Cahill out of the equation. The Spaniard tried to slot one into the corner of the net but Courtois makes a great save to block it. It comes back out to Ramsey who tries to scoop it over everyone into the back of the net but a deflection takes it out for a corner which comes to nothing.
More changes, Kieran Gibbs comes on for Ozil while Victor Moses replaces Terry. Eh?
Chelsea are getting closer. Zouma swings in an inviting cross into the box that Hazard flicks towards goal. There isn't enough on it however and Falcao can't direct it goal bound.
Hazard is hacked down by Arteta and Chelsea can load the box for the free kick. Fabregas tries to swing it in from the right but it is an appalling effort that fails to beat the first man and Arsenal clear.
That will be Oxlade-Chamberlain's last contribution as he comes off to be replaced by Mikel Arteta who makes his first appearance since November 2014.
Oxlade-Chamberlain tries his luck again from the edge of the area and his effort takes a wicked deflection off Zouma, but it only guides is straight into Courtois' arms.
Cech claims that corner at the second time of asking and Arsenal break menacingly. It comes across to Cazorla who creeps down the byline before threading a pass into Giroud. From six yards out, however, the Frenchman blazes over.
Despite Ivanovic's best efforts to put him off, Cech leaps across to palm away Oscar's free kick. Chelsea have a corner, but before they take it there is another Chelsea change as Kurt Zouma replaces Azpilicueta.
Free kick for Chelsea now on the edge of the box after Coquelin slides across Hazard. The Gunners midfielder is also booked and Chelsea have a real chance to work Cech from this set piece.
Giroud is involved straight away, peeling away from his marker towards the near post but he can't get a clean connection on Oxlade-Chamberlain's cross.
First change of the afternoon for Arsenal as Olivier Giroud replaces Walcott.
Oxlade-Chamberlain rolls Azpilicueta in his own half and springs forward, flicking the ball past Matic too before the Spaniard catches up to cynically haul the Arsenal winger down to receive a booking.
Ooof, what a miss from Hazard. Fabregas brilliantly turns Coquelin on the edge of the box and slide an equally sublime ball through for Hazard who has broken free inside the right of the box. Koscielny is racing across to put pressure on the Belgian and it works as he fires a wild shot over the bar. Rubbish effort
Chelsea go route 1 with Fabregas lumping a ball over the top for Falcao to run onto. He turns away from Mertesacker who is slow to react but his first touch lets him down, allowing the German to get back and hook the ball clear.
Oscar is quickly in the thick of it, cutting in from the left past Coquelin towards the edge of the box. Falcao is peeling off to the right ahead of him but the Brazilian takes the shot on instead. It was the wrong decision in the end; his effort was a poor one.
Another change for Chelsea here as Ramires comes off with Oscar entering the fray.
Ramsey slips a neat ball through to Cazorla on the edge of the D who wrong foots his marker before sliding a neat ball through for Ozil to run onto but he over hits his pass.
Falcao receives the ball and cuts inside from the left, looking to curl one into the top corner only for Monreal to block his effort.
One change to bring you as the second half kicks off, Radamel Falcao enters the fray to replace Loic Remy.
