Not an excuse for losing the match, as Arsenal were outplayed much of the game, but has to be pointed out:
1. Coquelin fouled by Ramires during build-up to first goal, not given
2. on the PK given, Ramires went down without being touched. it was actually a dive when he realized he couldn't get around the GK
3. A.Cole professional foul on Sagna running behind the defense towards goal - red?
Just how it goes, unfortunately.
wonder if the Ramires PK was a "make-up" for the earlier non-call
