Manchester United goalkeeper Edwin van der Sar has admitted he may call time on his lengthy career at the end of this season.

The Dutchman is currently sidelined following surgery on a hand injury.

"I've said for a few years that it sometimes may be my last season," he revealed.

"Six months before my contract with Manchester United ended in December 2006, we extended for one year and so far it has been the same every time.

"I wait each season to see how or where I stand, if everyone is happy and if I can get motivated.

"But I know, because I always get older, it is increasingly likely that this will be my last season.

"In December, it will be clear how it goes. By then, I'll have clarity. It is a horrible dilemma."
