Hamburg striker Ruud van Nistelrooy wants to play on next season.
Now 34, the Manchester United legend cannot rule out a return to former club PSV Eindhoven.
"Everyone knows how I think about that club," he confessed. "I have warm feelings for them.
"But it's too soon to talk about it."
Van Nistelrooy came close to a move to Tottenham when leaving Real and a return to the Premier League cannot be discounted, where the likes of Blackburn Rovers and Wolves would jump at the chance of landing the Dutchman.
