Former two division champion David Haye is placing his faith in Amir Khan. He believes the Bolton boxer is only man capable of bringing down Floyd Mayweather Jr. and his unbeaten streak. Khan defends his WBA/IBF junior welterweight titles against mandatory Lamont Peterson on Saturday night, but plans to make a move to welterweight in early 2012.

Khan wants to challenge Mayweather for his WBC title on May 5th, the scheduled date of Mayweather's return at the MGM Grand in Las Vegas. If a deal can't be reached for a unification between Mayweather and WBO champion Manny Pacquiao, then Khan becomes one of the leading candidates to face Floyd.

"The only way Khan could be the best pound-for-pound fighter in the world is by beating Mayweather," Haye told the Sun. "And I believe the only guy that can beat Mayweather is Khan. He's young and fresh so, if anyone has the physical tools, it's him."
