David Haye has once again refused to rule out a return to the boxing ring despite his recent retirement.

The former WBA champion, who has expressed his desire to pursue an acting career, recently kept his promise to quit the ring on his 31st birthday.

However, Haye has repeated his claim that a fight against either Wladimir or Vitali Klitschko would be the only challenge to tempt him back to the sport.

"You never know, there's always another chapter, whether it's me retiring and you never hear from me again, or because I go out there and become a big success with the acting," he said. "It's the end of one chapter and there are plenty of chapters to come in the rest of my life.

"Only time will tell whether the Klitschkos need me more than I need them.

"They won't believe that. But it depends what they want out of boxing. If they want guaranteed easy victories then they can do what they've always done but if they want a tough challenge you'd think they would want to beat down my door. But if they're not interested in fighting then fair enough, I've moved on. It obviously wasn't meant to be."

Haye's last fight was his title defeat to Wladimir Klitschko in July.
