Yeah, real obvious it was broken when he walked off the first time.
I fucking love Coquelin every game. It's so refreshing to have a player play a focused game in our team. Too often we see our players asked to do far too much due to Wenger's desire for players to "express" them self.
Coquelin heads the other way - he plays with restraint and in turn it lets him do the basics well. Doing so lets others around him know what to expect, what responsibility to leave to him, etc.
