David Haye fully expects Wladimir Klitschko to be fit enough to fight him this summer.
Londoner Haye has finally agreed a deal to put his WBA title on the line against IBF/WBO holder Klitschko on June 25 or July 2.
It emerged today the Ukrainian's elder brother Vitali, who puts his WBC title on the line against Odlanier Solis on March 19, will step in should Wladimir's abdominal injury fail to heal in time.
The injury has twice forced Wladimir to pull out of a proposed fight with Dereck Chisora, but Haye would be surprised if the 34-year-old did the same with him.
"I don't expect that," he told Sky Sports News. "With me he's going to take his training very seriously, he's going to make sure that there's going to be no injuries that can affect this fight.
"And if there is any problem then his brother's going to jump in.
"But I've got a feeling whatever injury Wladimir has or is carrying will be fine by the time he gets in the ring with me."
He continued: "I think that's the biggest fight in the world. He's the guy who's ranked number one by a lot of experts, he's got the Ring Magazine belt. He's the guy I'm going after.
"If for some reason Wladimir isn't able to compete on that night then his brother should step up. I think that's the fair thing to do.
"First up is Wladimir, then his brother."
The fight was expected to be held in Germany, where the Klitschkos have a huge following, but the their manager Bernd Boente revealed today "two or three" other venues are being considered.
A British venue was never an option, though.
"He's the kind of guy who likes it his own way," said Haye. "He's used to calling the shots.
"I don't believe he would have fought me in the UK, even if we'd found a venue that he'd generate more money in.
"I had to concede that the only way he's going to fight me is in Germany.
"He said it was a deal-breaker if he had to come into the ring second. Okay, whatever.
"I conceded a lot of things because I know as soon as I get him in a ring with me, I'm going to knock him out."
