Manchester United fullback Luke Shaw has cast doubt on making their clash with Arsenal.
Louis van Gaal is already sweating on the fitness of David De Gea, Phil Jones, Jonny Evans, Michael Carrick, Rafael and Radamel Falcao for the game at the Emirates.
Daley Blind and Marcos Rojo are definitely out.
And Shaw is also now a doubt for the weekend after revealing he picked up 'a few knocks' during England's 3-1 Scotland on Tuesday.
Shaw said: "I picked up a few knocks during the game and my left hamstring, which I hurt at the start of the season, I could feel a little bit.
"We had a discussion at half time over whether to bring me off then but it was a game I didn't want to come off in so I played the extra 15 minutes and then Roy decided to sub me off.
"We will just have to see but I am hoping to be fit."
