Haye relying on Lewis' help against Klitschkos
In his final fight before retirement, Lewis stopped Vitali Klitschko in the sixth round of their June 2003 clash after a sizeable cut opened up above the Ukrainian's eye.
Vitali had every reason to feel aggrieved by the premature finish, as he was comfortably ahead on all three of the judges' scorecards.
But despite Lewis' struggles, Haye believes he has the know-how to boost his bid to defeat both of the siblings before retiring from boxing in October.
"If there's anyone who knows how to beat a Klitschko, it's Lennox," Haye told the Daily Star. "He beat a prime Vitali. Lennox was way over the hill but still ripped Vitali's face to shreds and won the fight. Lennox also knows what Wladimir's trainer Manny Steward knows, because he was trained by him."
Vitali's most recent defence of the WBC strap, against Odlanier Solis on Saturday, provided an underwhelming spectacle, with the Cuban unable to continue after picking up a knee injury in the first round.
Although Vitali refused to rule out the prospect that Solis had exaggerated the extent of his problem, scans have subsequently shown that he suffered a torn cruciate ligament.
