They're top heavy in midfield, week up front and in defence I think, there's still a pretty big imbalance.
Herrera, Carrick, fellaini, Di Maria, schweinsteiger, schneiderlin, mata, blind. That's an awful lot of competition for 2/3 spots.
Then they've got Rooney and Wilson as strikers (hernandez looks like he's away).
They've still got a bit to go to get balance I think.
