Amir Khan has been given renewed hope that he could be Floyd Mayweather’s next opponent.

Mayweather’s father and training, Floyd Mayweather Snr, says the Briton is “number one on the list” of potential fighters for his son to face, though he admits that situation could change.

Khan was ringside to watch Mayweather beat Argentine hardman Marcos Maidana in Las Vegas on Saturday – the 47th straight victory of his unbeaten career.

The American great has suggested that he may only fight twice more, and two victories would bring him level with Rocky Marciano’s perfect record of 49 out of 49.

Manny Pacquiao is the man many want him to face, but Mayweather Sr. is quoted by Hit First Boxing as saying: “More than likely it won’t be Pacquiao. I would say Amir Khan is number one on the list, but that’s still not even permanent. There’s still a few other fighters out there. I can’t say who’s permanent unless they ask for it.”

Khan taunted Mayweather in the aftermath of the Maidana win, saying: "After seeing him win I believe I will beat him.

"Floyd, as we all know, isn't the biggest puncher. His footwork has slowed down, he only throws single punches and gets hit a lot more. We all know Maidana isn't the quickest, and he still got through with shots.”
