Amir Khan has said he will not make the same mistakes in his rematch with Lamont Peterson in Las Vegas in May.
Khan still feels aggrieved about the outcome of the first fight, a split decision that saw Peterson take Khan’s WBA and IBF light-welterweight titles.
The Bolton boxer admitted for the first time that he struggled to make the weight for the bout last December.
“I made a few mistakes in the first fight but I still felt I won it,” the 25-year-old said.
“For this fight, we’re going to change a lot of things. I’ll train hard and am not going to make any mistakes at all.”
Khan described the original fight as the best contest of 2011.
“It was toe-to-toe action and exciting,” he said. “It was tough and the next one will be even tougher because we know what to expect from each other.”
“We’ll see a different Amir Khan for this fight. I’ll be explosive, as always, and maybe this fight can be one of the fights of the year too”
Khan’s grievances over the original fight concerned points deductions by referee Joseph Cooper for pushing and also the role of ‘mystery man’ Mustafa Ameen at the ringside.
The pair face each other again on 19 May at the Mandalay Bay resort in Las Vegas.
“I’ve started training early for this fight,” said Khan.
“I wanted to get back in the gym and get into shape. I’m going to meet Freddie [Roach, trainer] next week to train at the Wildcard Gym [in Los Angeles] and then go to the Philippines for high-altitude training.
“I always train like a challenger and I want to bring those titles back to Britain.
“We’ll see a different Amir Khan for this fight. I’ll be explosive, as always, and maybe this fight can be one of the fights of the year too.”
Peterson, who has accused Khan of arrogance, said: “I decided to take the rematch not because of anything Khan’s team said or because I feel I have to prove myself to anyone, I took it because you all thought it was a great fight and that we should do it again.
“It seems Team Khan still have problems with what happened in DC. I can only tell them that nothing shady happened, but I’m sure they won’t take my word for it.
“I’ll be ready to die in the ring to keep these titles.”
