Van Der Sar arrived at Old Trafford in 2005 and has gone on to play a very important part of United's success.
Ahead of the Sunderland game this Sunday, Sir Alex Ferguson said: "We’re planning for it to be possibly Edwin’s last season".
He was then asked if he may stay and take on a coaching role at the club, the boss said: "He’ll be someone of interest in terms of his knowledge and experience, but we haven’t discussed that yet."
Man United will sign 26-year old Danish goalkeeper Anders Lindegaard as soon as the January transfer window opens.
Talking about the new signing, Ferguson said:
"We can't register him until after the Stoke game because of the Bank Holiday"
"But he is training with us now and that is important.
"It will bring him to a better level of fitness because he has not played for a few weeks. We will see how his progress goes."
