Valencia scoring against Swansea might be more of a problem in terms of team selection for this game. He is the one player who was the most pros/cons IMO as to whether he should play or not. On one hand, the goals he has scored this season might make people forget how average his overall play has been, he probably has the most uncompleted cross ratio in the league. However, he still does beat his man and eventually he's going to find a United player in the box if we can commit players fast enough. He will also help out Rafael with Hazard and usually gets the better of Cole against Chelsea, even if it doesn't lead to a victory. I think the fact he scored and that he will do his defensive duty will mean he is going to play on Sunday, no matter how much some fans don't want him to.
Welbeck is in his best scoring form ever, so he's not going to be dropped and I doubt we'd see something like Januzaj dropped for Rooney to play in the middle with Welbeck on the left (and Valencia on the right). Making way for Cleverley or Giggs to drop into midfield with Carrick and Fletcher. If Rooney makes it back, I'm sure it'll be Kagawa who is replaced. I don't think we'll see van Persie here either.
de Gea; Rafael, Smalling, Vidic, Evra; Fletcher, Carrick; Valencia, Kagawa, Januzaj; Welbeck
Is the most likely line-up unless Rooney is fit.
We could play out of our skin here and still only get a draw though I reckon, so it's going to be a tough few weeks to get back in real contention of the top four. A win here would be huge if we got it, but I can only see at best a draw.
