I can't believe some people are saying anything like that was one of Utd's best performances in months.
Carrick gave the ball away in dangerous area's more times than most players would and I'm not remotely convinced by those stats as Carrick seemed to get a heck of a lot more than 8 passes wrong. Either way, pass completion means nothing, neither does possession. Utd were toothless in the first half, Hernandez was complete crap, Welbeck barely did anything despite having a decent run out time wise, screwed up everything he did(which wasn't much), the one time he managed to run with the ball he put in an awful pass behind Young when a pass infront of him would probably have led to a very good chance of a shot.
Rooney, Rooney didn't wake up till the shot he missed in the second half from range without too much power anyway(would have been saved if the keeper thought it was on target) then a freekick, which was also easily saved, and then his game stopped again.
Blackburn were pretty rubbish for the vast majority of the game, Valencia looked good, Young came on and got a great goal, other than that it was a pretty one sided "give ball to Valencia, he'll swing it in to no one, no one else is even awake" game. This is a game where utd playing brilliantly would have won... well 7-1 quite easily. The laboured into a 2-0 victory from two fantastic strikers(even if Robinson probably should have saved Valencia's), while requiring their own keeper to make the two best saves of the game.
Decent, never REALLY looked in trouble, but no where near great performance, average, maybe.
