Former unified heavyweight champion Wladimir Klitschko recently posted a video where the boxer left the door open for a future comeback.

Back in April, Klitschko returned to the ring for the first time since suffering a twelve round decision loss to Tyson Fury in November 2015. This time he faced Anthony Joshua before a crowd of 90,000 at Wembley Stadium in London.

Klitschko had Joshua down and in trouble in the sixth round, but the younger man rallied in the later rounds to stop the veteran in the eleventh round.

There was a rematch slated for the fall after Klitschko made it seems that he was going to exercise a contract clause for a second fight.

Klitschko decided to go in another direction and announced his retirement from the sport. Joshua would instead fight, and defeat, Carlos Takam in Cardiff, Wales.

But Klitschko, 41, recently posted a video of himself back in the ring.

In the video, he walks around the ring before facing the camera to make several statements regarding his abilities and hinting at a return.

"It's my first boxing workout in almost a half a year out and you know what, I feel I’ve still got it. Maybe I’ll wait a couple of years and say I still got it" and return like George Foreman did into his mid-40s," Klitschko said.

And in an interview with the BBC he added: "Right now, I’m speaking of right now. I’m totally happy where I am, what I am and where I’m going. I’m 41 and maybe you know George Foreman made it at 45, maybe I’ll wait a couple of years and say I still got it and I feel like coming back.

"But, honestly speaking I wish to my self that I will never comeback, I wish. I don’t know what should happen that I’m gonna come back, I don’t know what, because I’ve been there - I’ve done that - I’ve seen it, as a fighter I give it all."
