"Also the injury of Wayne Rooney is more heavy [serious] than we thought"
Quizzed further on Rooney, van Gaal said: "It’s a nasty injury. It’s been getting worse but we have to let him train to make the ankle stronger, that’s very important. I cannot say [how long he's out for] because the doctor shall decide that with Wayne of course. He is training well in the rehabilitation."
I'm not concerned. Van Gaal has had plenty of opportunities to play Wilson and he has still remained on the bench. United will be in for a big striker come January which is where the 28 day period almost lasts until.
