Manchester United boss David Moyes insists Marouane Fellaini will prove his worth.
The midfielder is out for six weeks after undergoing wrist surgery.
"I have no doubt he will eventually be a good player for us," said Moyes.
"He has been unlucky. He has not felt 100 per cent because of his wrist and has been finding it difficult.
"I asked him to see if he could get over the Christmas period. He got the back injury against Everton and since then he has never really been right."
