Manchester United midfielder Tom Cleverley who picked up a foot injury against Everton in October and was initially expected to be back after the international break, but he will now be forced to sit out for much longer to recuperate.
Sir Alex told reporters: "It is pretty long term, (he will be out until) Christmas time, it is unfortunate. It is worse than we thought.
"When he first came off against Everton he reported it as just a tightness, with a bit of pain. We have done scans again and the injury has recurred. We will have to give him a break."
