Amir Khan is confident he has turned over a new leaf ahead of his return to the ring against Carlos Molina in the early hours of Sunday morning.
The Briton has left trainer Freddie Roach since suffering a second defeat in succession against Danny Garcia this summer, when he was knocked out inside four rounds.
Khan has acknowledged the need to change his style and he is confident he will return to winning ways against the unbeaten American in Los Angeles.
"I'm a wiser, smarter, more mature fighter and on Saturday I'll be ready to show that," he said.
"I'm only just 26 and people forget how young I am. I'm still a baby in the sport of boxing and I did everything so young. I'm already a two-time world champion but there's still a lot to come.
"My new trainer Virgil Hunter has taught me so much and there's more I can do. You'll see more from me in this fight. You'll see a new Amir Khan.
"I got caught with a shot against Garcia. Look at how Manny Pacquiao got caught the other day by a guy he should have beaten. That's the sport we're in, where one punch can change a fight.
"I believe I won the fight against Peterson in my previous fight but I just didn't get it. But against Garcia I made a mistake and I paid for it. That's one of the reasons I changed my trainer and trained a lot of things about my career.
"I'm a smarter, better fighter now."
