Manchester United goalkeeper Edwin van der Sar is travelling to Holland for a new scan on his knee injury.

The 39-year-old has been missing since mid-November after suffering a blow on the knee in a collision with Everton's Tim Cahill at Old Trafford.

It was originally thought the veteran Dutchman would only be missing for a couple of games.

However, with the Christmas programme approaching and no return in sight, Sir Alex Ferguson revealed van der Sar is to see his former national team doctor.

"Edwin is going back to Holland," said Ferguson.

"It is a change of scenery for him and the Holland team doctor will have a look at the injury.

"He has never had an injury like this in his life before so we think it is a good idea and expect him back in a couple of days."
