Wladimir Klitschko has left the door open for David Haye to secure another fight against him or his brother, Vitali.

Haye originally retired from the sport after losing to Wladimir last year, but made his return earlier this month when he knocked Dereck Chisora out in five rounds.

Haye immediately set his sights on a fight with Vitali, but with the WBC champion eager to climb onto the political ladder, there had been speculation that the fight wouldn't go ahead.

However, Wladimir has insisted that it is still a very real possibility.

"It's very difficult to follow what David Haye wants - retirement, not retirement - fighting or not fighting Vitali or me, fighting someone else," the IBF, WBO and WBA champion said.

"Eventually fighting me which was great following all the talk, and I think the chances are there (for another Klitschko fight). And as I said, I think that David became a better person and I hope that he is more reliable than he used to be.

"We'll see the next step. The next step is for Vitali to fight. It's very important for him to win the fight and then we'll continue to talk."

Vitali's next fight comes against the relatively unknown Manuel Charr.
