you also have to wonder why players put themselves in the wall if they do all they can to avoid the ball. kind of defeats the purpose. frustrating to lose to such a cowardly act.
That and Tevez walking away from the wall when you'd think he'd have enough time to break off and shut down Rooney if the short pass was played, both were a bit bizarre. Don't know what Nasri was playing at. Perhaps some defensive leadership that left the pitch with Kompany would have made the difference there.
If Nasri had just got completely out of the way then it almost certainly wouldn't have been a goal, by just sticking a leg out he well and truly fucked that.
