David Moyes has revealed a number of his Manchester United players are nursing injuries, with the biggest worry concerning star striker Robin van Persie.
Van Persie was in hot form for the Netherlands national side during World Cup qualifying week, firing a hat-trick in the win over Hungary last Friday.
We've got a few who came back with a few bumps and bruises. Probably the one we're most worried about is Robin van Persie.
We're a bit worried about Robin and the condition he's come back in. We'll see how he is tomorrow.
He got a kick in the calf and he came off at half-time in the second game. He had a kick in the calf and he also had problems with his toes as well. We'll see how he is.
Manchester United face Southampton on Saturday afternoon, and van Persie will have to prove his fitness on the morning of the game.
Moyes also confirmed Antonio Valencia and Javier Hernandez will be monitored after coming back from their long-haul trips with Ecuador and Mexico respectively.
However, Moyes also confirmed, in a piece in the Belfast Telegraph, that the midfielder could continue to play in the short term, saying:
Fellaini needs an operation. It is quite a bad wrist injury. There is a bit of bone and ligament sticking out.
We have been told we can get away without operating just now and we are a little bit short with Tom Cleverley picking up a calf strain for England, so we need him and we will put it off as long as we can.
