AMIR Khan believes his reunion with trainer Virgil Hunter has given him the belief he can upset the odds and become a world champion again in New York tonight.

The 32-year-old Boltonian takes on undefeated American Terence Crawford at New York’s Madison Square Garden looking to snatch his WBO welterweight crown.

And while he may be the underdog as far as onlookers are concerned, Khan is confident his preparation back with former coach Hunter on the west coast of the US will see him ready for fight night.

Khan told the pre-fight press conference: “This ranks at the top for me because I’m fighting a world champion – it is a great motivation for me, to know I’m fighting the best out there once again.

“And it makes me train harder, work harder and focus on this fight. I know I can’t make any mistakes because I could be trouble. I’ve been watching all the videos of his fights. I see how he breaks down fighters, how he sees openings and stuff, and I can’t make those openings.

“Maybe my last performance got me this fight. To me, that wasn’t the best performance. That wasn’t the best Amir Khan.

“I’m now back with my old trainer, Virgil Hunter, where I’m happy and he trained me the best. And he knows me better than any trainer out there.

“We know we’ve done everything we have to do for this fight, and I’m going to be more than ready.

“I’ve had some good fights in the welterweight division. We fought {Luis} Collazo. We fought {Devon} Alexander.

“Virgil has brought the best out of me. Even the Canelo fight was going well until I got caught.

“Every fight with Virgil, I’ve learned something from, win or lose, and he’s brought the best out of me. I needed to get back with someone who could bring that respect back for the sport of boxing and also make me work harder.”

“This is a dream come true, and hopefully on Saturday, a dream will come true, where I get my opportunity to fight for another world title and be one of the best pound-for-pound fighters in the world.

“You can’t deny that he’s (Crawford) a good fighter. I know he’s training hard because he doesn’t want to lose that unbeaten record, and I don’t want to lose because I want to achieve everything in boxing.”
