5 Live Boxing: Ricky Hatton, Floyd Mayweather Sr, Joe Calzaghe, David Haye and Amir Khan Radio 5 Live: Tuesday 7 October, 2000-2100 BST
Khan was knocked out in less than a minute in his last fight
Britain's Amir Khan is confident he can rebuild his career under the tutelage of renowned American Freddie Roach.
The 21-year-old has moved to Los Angeles to work with Mike Tyson's former trainer following September's stunning defeat by Breidis Prescott.
"Freddie is one of the best coaches in the world," Khan told BBC Radio 5 Live.
"He's brought the best fighters on - Tyson, Bernard Hopkins, Oscar de la Hoya, Manny Pacquiao. That's a massive confidence boost."
Former Olympic silver-medallist Khan lost his unbeaten record in spectacular fashion when he was knocked out by Colombian Prescott inside a minute.
Khan initially pledged to stand by trainer Jorge Rubio, who had recommended Prescott as an opponent, but changed his mind and ditched the Cuban after one fight together.
The lightweight insists he will learn the lessons from that defeat in Manchester.
"It was difficult but I had to go home and watch the video. After watching it, I knew exactly what I did wrong and how I could have done things differently by not rushing in.
"Overall, the gameplan was wrong.
"What I like about Freddie is that he explains what he wants you to do in a fight, even in training.
"With my previous coaches, we didn't really have that gameplan. We just went in there and did things naturally."
Khan also believes working alongside four-weight world champion Pacquiao, who is currently preparing to face De la Hoya, will help his development.
"After Manny, I'll be the second guy Freddie spends all his time with," said Khan.
"Training alongside Manny and all those other fighters, it puts me in a good position to learn. In England, I'd be in the gym, isolated, training on my own. It's a lonely place.
"When you're in a gym with champions, and other kids who are hungry, it brings more out of you."
Khan was linked with Roach after sacking Oliver Harrison in May this year, but made the surprise decision to employ Rubio instead.
