Amir Khan (31-3, 19KOs) believes that he's taken the toughest fight possible on Saturday night - even tougher than a clash with Floyd Mayweather Jr.
Khan had tried to get a fight with Mayweather for several years, but the fight never happened.
Mayweather retired last September, at 49-0, after winning a twelve round decision over Khan's stablemate Andre Berto. In a recent televised interview on Showtime, Mayweather opened the door to a potential comeback by the end of the year for his 50th fight.
Khan will move up by eight pounds to challenge Saul 'Canelo' Alvarez at a catch-weight of 155-pounds for the WBC middleweight championship at the T-Mobile Arena in Las Vegas.
The British superstar is a big underdog in the contest. He feels a Mayweather fight needs to take place - if he upsets Canelo on Saturday night. There are several factors to prevent that. For starters, Canelo has a rematch clause in place. The second, the World Boxing Council has ordered the winner to make a mandatory defense against IBO/WBA/IBF champion Gennady 'GGG' Golovkin.
"I think the Mayweather fight has to happen if I beat Canelo," Khan told Sky Sports News HQ. "Styles make fights and I really believe a fight with Mayweather would be easier than a fight against Canelo.
"Canelo has got that physical strength whereas Mayweather would be like a game of chess. I've got a massive fight with Canelo in front of me and by winning this fight it would definitely take me on to the biggest fight of my career and a bigger one than the one I'm going to be facing on Saturday."
"This has to be one of the biggest fights of the year because everybody is talking about it. You've got a puncher versus a boxer. You've got two different styles and you've got the whole world tuning in for this fight. Just walking the Strip and talking to people about the fight helps you understand what this fight is all about."
