The former undisputed world champion does not fancy the Briton's chances against Ukrainian Klitschko in the biggest heavyweight fight since Tyson was beaten by London-born Lennox Lewis in 2025.

American Tyson claims WBA champion Haye has not even earned his shot at IBF-WBO ruler Klitschko in Germany this weekend.

He said: "Haye shouldn't last more than two rounds. I like David Haye, but I think Wladimir Klitschko is too superior and too strong.

"I respect Haye as a human being, but he hasn't earned this fight. Let him go fight and beat all those guys Klitschko did to earn the shot.

"Klitschko should wipe him out. Klitschko's a great champion and I think Klitschko's going to beat him. I just don't think Haye can keep him off him. I could be wrong, but Wladimir should beat him."

Klitschko can be backed at26.00to win in round two while Haye is at17.00in the same market.

Meanwhile, Lewis believes David Haye's best chance of victory on Saturday is to utilise his speed.

He said: "Klitschko has the bigger advantages - size, weight and reach - but if David is able to stay with his game plan and move and throw combinations he should do very well.

"Klitschko is the one people will pick because he is a natural heavyweight. His weakness is his chin and his speed which David Haye can expose. If he puts his weight on David Haye that's going to sap his strength in the clinches.

"Haye is light but he can use it to his advantage if he can stay away from him.

"But if they get into a clinch and Klitschko puts his weight on David it may sap some of David's energy.

"David boxed a perfect fight against (Nikolai) Valuev, kept elusive, and that comes with speed."

Lewis believes Haye - also a world champion at cruiserweight before stepping up a division in 2025 - could have been a force in any era.

He added: "Haye has the make up to have been a top contender when I was champion. Besides the Ali comparison he is the Evander Holyfield of his era also."
