Amir Khan has promised to show exactly what he is capable when he fights the dangerous Saul Alvarez in May.

The British boxer has jumped two weight divisions to meet the Mexican, nicknamed Canelo, for their huge Las Vegas fight on 7 May.

Alvarez, who beat Miguel Cotto to win the vacant WBC middleweight title in November, has lost just one of his 47 fights, to pound-for-pound king Floyd Mayweather in 2013, winning 32 of his bouts by knockout.

Khan has not fought since beating Chris Algeri in May last year, but insisted fans will see "a different Amir Khan in this fight."

"I really promise you're going to see a different Amir Khan in this fight," he said at a press conference.

"I've been let down so many times in having the biggest fights. There's a lot of big names I've wanted to fight but just couldn't get those fights.

"This is my time now to shine. I want to show the world how good Amir Khan is.

"I'm up against a guy who is a great fighter. Alvarez is a dangerous fighter, he's strong.

"A lot of people are saying to me, 'why do you want to move up to middleweight and fight this huge fighter, this huge puncher?' and I said 'look guys, I really believe I can win this fight'.

"I know I can take his power, take his speed and I really have the tools to win this fight."
