United will travel to the Etihad without Nani, Antonio Valencia, Tom Cleverley, Nemanja Vidic and Anderson whilst Shinji Kagawa has an outside chance of making the bench but is likely to be left out and instead face Sunderland.
Despite the number of important players missing from his team, Sir Alex believes he has the squad to deal with this:
“Tom Cleverley will have a scan this morning and we’ll see what he’s like. It’s his calf injury, which is a worry, but we’ll see.
“I thought Kagawa may have done enough to make the bench on Sunday but I don’t think he’ll be available until the Sunderland game.
“Vida, he’s doing well in training but I think the game on Sunday is a bit soon. I think he’ll be ready for Sunderland.
“Nani and Valencia are still out. It will be a few weeks with them.
“I know we’ve got a few injuries at the moment but we’ve got a big strong squad of players.”
Despite the absences, Sir Alex is hopeful his side can pull a surprise and beat City at the Etihad, handing them their first defeat there in 2 years:
“It’s a derby game and they’re notorious for surprises. City haven’t lost for two years at home so it’s going to be difficult. It will be hard but we’re capable of beating anyone, as we’ve proved time and time again.”
