We actually played well for the first half in good control of the game but with no real penetration or shots around their area. Then the second half started, and i guess Moyes must have flown in from Spain and given the talk and the tactics because after that, even though Southampton stepped it up, we were nothing like the team from the first half.
It also seems that not just in this game but earlier ones too, Mata has good opportunities to play in Di Maria with a through ball but instead chooses not to and to play it square. Same with Rooney now and then too, almost like they have been told not to try through balls unless its a 6 yard one.
Finally the substitutions put the nail in the coffin for this game, we lost all pace going forward with Di Maria going off. Then Herrera came one and did nothing and worst of all Blackett came on and we lost the brains of Blind at the back and thus got caught, plus the fact Shaw was playing well to begin with. Now if Shaw was carrying a knock then just slot Di Maria or Januzai in there don't mess with the defence that has been doing okay for once.
