Canelo Alvarez vs Amir Khan

Amir Khan insists he would likely not be interested in any future showdown with Floyd Mayweather Jr. The 2004 Olympic silver medallist is currently in the final stages of preparations for his biggest professional test to date on 7 May, when he jumps two weight divisions to challenge Saul "Canelo" Alvarez for his WBC middleweight title at the newly built T-Mobile Arena in Las Vegas, Nevada.

Mayweather called time on his illustrious career with an unblemished 49-0 record following a routine points victory over fellow American welterweight Andre Berto in September 2015. Many have speculated, though, that the 39-year-old will not remain inactive for long, with only one more win needed to surpass Rocky Marciano's unbeaten streak.

Mayweather hinted at a potential return on 30 April during his role as promoter for Badou Jack's WBC super-middleweight defence against Lucian Bute. Revealing that he has held talks with CBS and Showtime, "Money" claimed he was currently happy on the promotional side of boxing but suggested he could step back into the ring for a nine-figure payday.

Along with the likes of Danny Garcia and the winner of June's bout between Keith Thurman and Shawn Porter, Khan would inevitably be touted as a possible contender for such a lucrative fight if he defies the odds to inflict only a second defeat upon popular Mexican Canelo during Cinco de Mayo weekend. However, the former WBA and IBF light-welterweight champion was overlooked for Mayweather's final fight despite repeatedly stating his case, and no longer appears as eager to make it happen.

"He messed me around a lot so I don't think I'd take that fight," he was quoted as saying by Sky Sports. "He messed me around, so I'd probably treat him the same way. Floyd's probably missing not having his picture on the MGM. He must see my picture and Canelo's picture and think, 'People have forgotten about me'. As soon as you say you're retired, we do forget about the people who say that.

"Mayweather's feeling that now, he's feeling like no one's talking about him, that he's old news, and maybe that's why he's trying to get everyone supporting him again by saying: 'I want to make a comeback'. Whatever Mayweather says, let him say it."

Canelo is a former opponent of Mayweather's, having lost his WBC light-middleweight belt via majority decision at the MGM Grand Garden Arena in 2013. Since then, he has stopped both Alfredo Angulo and James Kirkland in addition to outlasting Cuban Erislandy Lara and picking up another world title with victory over Miguel Cotto.

Khan, who was also eager to face Manny Pacquiao before Pac-Man's retirement, bounced back from consecutive defeats to Lamont Peterson and Garcia by beating Carlos Molina, Julio Diaz, Luis Collazo and Devon Alexander. His last fight was a comfortable defeat of Chris Algieri in Brooklyn last year.
