Man Utd keeper Van der Sar: Retirement decision made in December
"I've said for a few years that it sometimes may be my last season," Van der Sar told Sportsweek. "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 where I stand, if everyone is happy and if I can still get motivated. But I know, because I always get older, it is increasingly likely that this will be my last season."
He added: ""In December, it will be clear how it goes. By then, I'll have clarity. It is a horrible dilemma. On the one hand I do not oversleep, I feel as good as a few years ago."
