Manchester United goalkeeper Edwin van der Sar admits plans to retire at former club Ajax are now unlikely.

"It's going well and I'm enjoying it, so I decided in December to do another year, then make a decision," said Van der Sar.

"I always said I wanted to finish my career back at Ajax but I didn't think I was going to play for so long at such a high level, so that's not going to happen now. And it's quite a step down to go to a smaller club in England when you've played with such good players, so I don't think I'd do that. It's getting closer and closer to retirement time."
