Manchester United legend Ruud van Nistelrooy admits he may retire at the end of this season with Hamburg.
Van Nistelrooy has made a lively start to the season at Hamburg, scoring six in five games, but he fears his incarnation of a centre forward is a dying breed in world football.
"I don't have long-term plans anymore," he told Frankfurter Allgemeinen Sonntagszeitung. "I have to listen to my body, so I can't say now that I'll be playing in 2012.
"I look at everything from year to year, see how it is going and then decide whether to carry on. I'm aiming to play consistently and well this season. Perhaps I'll carry on, perhaps not. I've no idea how long I have left to play.
"If Hamburg qualify for the Champions League it would be nice, but when I feel that it is time up for me then I have to go - in or out of the Champions League."
