I posted this problem on the nasri thread. It's one of the reasons we were a better unit using the 4222 with Milner in it, in the first third of last season. That steel he adds and that cover he gives attacking fullbacks, even if he's notionally an attacking wideman, was missed as soon as nasri got in the team properly before Xmas. It happens even worse on both sides when we go 352 against a decent team.
We are too narrow as a team, too reliant on full backs to get behind teams. That's why we get exposed in these areas sometimes. it was obvious before this game that their widemen v our full backs could lose it for us.
And by the way, it doesn't exactly make me happy that a fucking pundit is picking this up before our manager.
