Wladimir Klitschko has refused to rule out a return to a professional boxing ring and stated he will return to the sport for the right cause.
Klitschko (64-5, 53 KOs) last fought Anthony Joshua back in April 2017 before officially announcing his retirement in August despite talks of a rematch against the Brit.
However, it's been over a year since their meeting and the Ukrainian has hinted a comeback could eventually be on the cards.
"You never say never, things can change," Klitschko told 112 International. "People often switch careers during their lifetimes.
"Look at Arnold Schwarzenegger: he was an athlete, then an actor, then a politician, than a businessman, and now he's involved in taking care of the planet.
"Maybe if I feel the time is right to help a certain charity, I'll get back in the ring."
When quizzed over returning to the ring professionally, he refused to rule out a another appearance.
"I had great times in the 27 years I spent in the sport," Klitschko answered. "I learned a lot and I traveled a lot, which was my goal when I first started boxing.
"I have achieved what I never dreamed of; I've done and experienced things that I had never even thought about. I've learned that when some doors close, others open.
"It's all life experience and sport really is amazing. I would quote Nelson Mandela: 'Sport has the power to change the world because it's a global thing'."
