Manchester United boss David Moyes is concerned over Danny Welbeck's knee injury.
Welbeck continues to shine in a central role and he followed up his two goals at Aston Villa with a goal and assist against West Ham United.
However, he was forced off just after half-time and he limped straight down the tunnel with a member of United's medical team.
"I've not actually had a chance to ask him yet," Moyes said, "He has come off with a sore knee so I'll need to check it to find out exactly what it was."
