Khan, who will meet Carlos Molina in Los Angeles on December 15, severed his ties with Roach following back-to-back defeats and will now be aiming to return to winning ways against the unbeaten American.

The former World Boxing Association and International Boxing Federation light-welterweight champion cited a lack of training time with Roach as one of the major reasons behind his decision to change trainer and is hoping things will be different under Hunter.

Khan said: "We have changed a lot of stuff for this upcoming fight, first of all the trainer, which I think is a massive part of the camp. The reason I had to change is because when you are always winning a fight you never look at the bad points, but when you lose you sit down with your team and you go through the whole camp and where you think you went wrong.Freddie is a great trainer but I wasn't getting everything I wanted. Freddie is a very busy guy and one of the best trainers in the world. I personally was the one who called Freddie and told him that I would no longer be training with him."

The 25-year-old also confirmed he had spoken to several trainers, including Floyd Mayweather Sr, but was comfortable with Hunter and felt he was the right man to progress his career. "I spoke to Virgil and the first thing I said to him was that you have Andre Ward and I hope you are not going to be busy like Freddie was with Manny Pacquiao and I do get 100% of your time," he added.

"He made it clear he is going to be with me 100% and whenever I need him he is going to be there."

Following defeats to Lamont Peterson and Danny Garcia, Khan is all too aware that he is far from the finished article inside the ring and is ready to utilise the knowledge of his new coach.

He said: "I'm still not 100%. I've still got room for improvement and it is maybe going back to the basics and looking at where I make mistakes and improving them."
