I'd have to disagree about both sides playing good football. Chelsea were dreadful in the first half. Could easily have been 4 goals down at half time. They looked like total strangers who were playing blindfolded their passing was that bad.
The first goal should never have been allowed. Clear handball and the offside rule is open to interpretation but it suggests that it should have been offside as well. Clearly in Courtois' field of vision and made a movement towards the ball.
However it was early enough to recover from and you'd have thought the injustice Chelsea felt from the goal would have fired them up. Instead they played like they were warming up for a 7.45 kick off or already thinking about their holidays.
Fabregas should have started instead of Matic. There were massive gaps between Chelsea's holding midfielders and the front three. Not helped by the inability to find a blue shirt.
Played into Arsenal's hands with too many long balls forward which either Mertesacker won or landed at an Arsenal player's feet.
Then, after half time when Chelsea just looked like they might have been getting a foothold in a game they'd have been dead and buried in had Arsenal's finishing been better, Moses commits an act of unforgivable stupidity.
Most players on a yellow card have the sense to do everything they can to avoid a second one. What does Moses do, blatantly dives in the box, which is inexcusable in itself, and leaves Chelsea with 10 men.
Even with the equaliser it was never going to be an easy task to win, so switching off straight away afterwards was a killer.
Chelsea were very lucky to lose 2-1. Outfought and outplayed by Arsenal on the day. Why it was such a lacklustre performance from Chelsea who knows, perhaps they were overconfident because of Arsenal's defensive crisis. Whatever it was, the best team by some margin won on the day.
