It seemed to me that the plan was to overload the midfield, hound Toure, and to break forward in numbers when they won the ball.
The latter part of that plan kinda worked, cos anytime they did nick it they stormed forward quickly with Fellaini coming in from the left of the box - their problem was the continually poor final ball, and their lack of a number 9. None of Fellaini, Mata, Cleverley looked at all like scoring, and City did well to force Rooney away from goal.
The problem with that midfield though is that out of the 5 of them there's not one player who could account defensively for Nasri or Silva, who ran riot coming inside and overloading Carrick. Silva just kept dropping into the gap between Evra and Carrick (to the side of the hole) and no one knew how to pick him up.
It's just rank bad management and set-up from Moyes. He didn't even have the nous to change it, he just sits there looking worried. He's one million miles out of his depth.
Don't you think that's his natural tendency nowadays? He always comes back looking for the ball, and is as eager to start off sweeping moves as he is to finish them... Bodes well for England as he can play behind Studge
