A red card 5 minutes into the game would obviously have repercussions sooner or later. Looking at the buildup to Arsenal’s first goal (Nasri, 20′), it appears to have been the former. Arsenal made nearly 20 more passes than City over the 10 minutes leading up to the goal, and you can see from the Guardian chalkboards below that they were running the midfield from front to back. Isolated groups of Man City players were trying to maintain the ball while waiting for players to support, but having one less man leaves too may holes to fill and Arsenal plugged them full of attacking movement.
Video highlights of the match below–the first of which is Boyata’s early foul of Chamakh and subsequent red card, and the second of which is Nasri’s goal–a great finish off a quick give&go with Andrei Arshavin (as indicated by the white circles in the top chalkboard above):
