British welterweight contender Amir Khan believes he can bring Floyd Mayweather Jr.’s career to an inglorious end, by inflicting a first defeat on the American superstar.

Mayweather’s classy one-sided points win over Manny Pacquiao last Saturday at the MGM Grand, Las Vegas, stretched his perfect record to 48-0, including 26 knockouts. Now THE RING, WBC, WBA and WBO welterweight holder says he will have one more fight – in September this year – before retiring. Trainer and father, Floyd Mayweather Sr. is suggesting Khan would be a good choice as his son deserves to bow out with an “easy fight.”

As ever, Khan, who faces Chris Algieri at Barclays Center in Brooklyn on May 29, is keen to take up that challenge, utterly convinced he has the arsenal to unhinge 38-year-old Mayweather. However, Ramadan means Khan, a devout Muslim, would find it impossible to be ready in time for September.

So, if that fight does not materialize, the Bolton man could well push for a match-up against Pacquiao instead.

“I think Mayweather’s team are wanting the fight. On the other hand, I’ve even spoken to Manny’s team and they said the same to me,” said 28-year-old Khan (30-3, 19 KOs) to BBC Five Live. “But Mayweather’s the one I want because I really believe I have his number.

“I’m ready for whatever Mayweather wants. I think it would be an amazing fight because I believe size is a really big factor between me and him, and the speed and the power as well.”
