Bolton boxer Amir Khan vows to win back his world titles in 2013

Bolton boxer Amir Khan has vowed to win back his world titles in 2013.

The Olympic silver medallist lost both of his light welterweight belts to Danny Garcia over the summer. He's since parted company with Hall of Fame trainer Freddie Roach and left his long time training base in Los Angeles.

But today he was defiant at a press conference to announce his comeback fight against the undefeated Carlos Molina.

"It hasn't been a good year but I'll come back," he declared at London's Mayfair Hotel. "Mentally I'm prepared and I know the change in trainer and in training camps will be a massive help. I still have a lot to learn but I know Virgil Hunter will help me with that. I could have taken an easy opponent for my next fight but I haven't. Any undefeated fighter is a good fighter so I'm not taking Molina lightly. But I need to beat him with a good performance and then I can look to becoming world champion again next year."

The Khan-Molina fight will take place at the Los Angeles Sports Arena on Dec 15th.
