Vitali Klitschko has said that he would be "happy" to knock out David Haye.
The Ukrainian was speaking in the ring following his brother Wladimir's four-round win over Jean-Marc Mormeck in Dusseldorf.
"It would be great - I gave him a proposal many months ago. David Haye thinks he's a world champion, he's not world champion anymore," the 40-year-old told Sky Sports cameras.
"Nobody knows what will happen tomorrow. Maybe in the next couple of months a Klitschko will fight David Haye, it would be a great fight."
The WBC heavyweight champion added: "I would be happy to fight David Haye, I would be happy to knock him out."
Vitali's last fight saw him overcome Dereck Chisora in a unanimous points verdict in Munich.
