Amir Khan immediately shifted his focus towards Floyd Mayweather after earning a lopsided decision victory over the dangerous Luis Collazo. Many observers feared Khan had bitten off more than he could chew by agreeing to face former world champion and veteran welterweight campaigner Collazo on his bow in the 147lb division.

Yet the Bolton fighter - whose last bout was in April 2013, when he struggled badly against the lightly regarded Julio Diaz - showed his class in Las Vegas by knocking down the rugged southpaw three times en route to a unanimous decision victory.

Khan was in no way flattered by two judges scoring the bout 119-104, with the third having it 117-106, as his superior hand speed and much-improved defence frustrated Collazo, who had won his last four fights, including a shock second-round knockout win over highly-rated Victor Ortiz last time out.

The pound-for-pound king extended his remarkable record to 46-0 after grinding out a majority decision victory over Marcos Maidana in the main event at the MGM Grand, and Khan, who has been linked as a potential opponent for Mayweather for some time, is keen to seize his chance now.

"People want to see a fight between me and Floyd," Khan said. "Floyd hasn't seen speed. He's fighting people with explosive power. But styles make fights and I think my style will give him a lot of trouble.

"Floyd looks beatable. He's getting a little older now and that's why a lot of people want the fight now because they want a young lion to come up and they want to see him get beat. I think the only person who has the chance to do that is me."

However, the bout will definitely not happen in 2014 as Mayweather's next intended fight date in September is too close to the Muslim fasting period of Ramadan for Khan.

That is perhaps just as well for the 27-year-old Khan, as no sooner had Mayweather's win over Maidana been announced than the two combatants began talking about an immediate re-match.
