The 40-year-old Dutchman, who made his debut for Ajax in the 1990/91 season and subsequently went on to play for Juventus and Fulham before joining United in 2005, would like to spend more time with his family and wants to end his career while he is still at the top of the game.
In an extensive interview with MUTV, to be aired on Thursday at 18:30 GMT, van der Sar says his decision was not reached quickly or lightly. “It’s been coming for a while,” he said. “After playing for so many years, you reach a point where you have to make a decision.
“There are a couple of things to consider – whether you still have an appetite for it, your family. You have to look at yourself also. You have to ask if you can bring that top level of performance that you need at United. At the moment I am quite happy with my form and my achievements on the pitch. I just want to [leave] that on a high level.
