Amir Khan insists his trainer did not take him to task over being dropped in his last fight.
Khan had to climb off the canvas to outpoint Samuel Vargas last year as he struggled to beat his unheralded opponent.
The Brit worked with Joe Goosen for his last two fights but has returned to San Francisco with Virgil Hunter after the trainer recovered from a life-threatening illness.
Khan is currently preparing for a much tougher challenge against world champion Terence Crawford in New York on April 20.
And he revealed Hunter was relaxed about his charge's below-par performance.
"I should never be put down by a guy like Vargas," he told BT Sport . "I got caught with an overhand right - I saw it coming but I just didn't move, I was too relaxed.
"I got caught with it and I thought 'damn, that shouldn't haven't happened'. I wasn't hurt, it was just a flash knockdown, but I shouldn't have been caught. I had to go back to my boxing and be smart.
"Virgil is quite cool, he knows sometimes anything can happen in a fight and that one big punch can land and put you down,
"He just wanted me to move forward, learn from the mistakes I made in the last fight and improve for the next fight against Crawford.
"There's no point looking back too far, it's all about improving and since I've been here I've been doing that. Defensively I'm a better fight and I'm moving better."
Khan is also confident his reunion with Hunter will propel him to an upset victory over Crawford.
"[Virgil has] known me for a long time, so it's always better to be with someone who knows you and your fighting style," Khan told ESPN .
"As you get older it gets harder [and] when you go to a new trainer, it can be hard to adapt to their ideas. Joe Goossen did a great job with two warm-up fights, but I've decided to go back to Virgil."
