UTd were lucky, Berbatov seemed to not be wasting posession, he'd hold it up, play it to Carrick/Fletcher/Park/Brown and they'd pass it straight to Villa.
I don't think they were that bad, Fletcher, Carrick, Nani barely started playing till the 80th min, at 2-0 down the midfield 4 actually started trying to play football.
Also worth noting Macheda didn't give away the ball badly before Villa's second, when you see the direction Macheda is running, he opens up a space knocks the ball down and Obertan should have picked it up and run through the middle, instead as Macheda peeled off to the left, Obertan ran to the left into the same space for no reason.
Awful first half, some good attacking footie by Villa, but woeful defending for the crosses, especially the second goal, two players, one should cover the potential inside cross and one the outside but an experienced Luke Young got in line behind Delfouneso. If Young just stood to his right that cross for Utd's second never makes it in. Good header by Vidic, and finish by Macheda though.
Don't think brown should have got a straight red, whoever the other defender was, was inline with them and probably would have gotten the first touch anyway, Young certainly wasn't clean through on goal.
