Khan, 25, is a former unified world light welterweight champion but his weak defence and suspect chin have seen him lose to so-called weaker fighters.
The Bolton scrapper, whose record stands at 26-3, was most recently knocked out by Danny Garcia, having escaped being beaten by Lamont Petersen after the American failed a drugs test.
This led many to call for him to retire, as being knocked out on several occasions bodes poorly for his future health, but Khan is sure new trainer Virgil Hunter will tighten up his defence.
Speaking at a London press conference confirming his December 15 fight with Carlos Molina, Khan said:
“(Myself and Hunter) have spoken quite a bit already. We discussed the fact that I am an offensive fighter, but now it’s time to be a smart fighter, to win fights with my brain.
“My main style was to be a boxer using my brain, but when you start to win so comfortably, you can forget the meaning of being a boxer. You can get drawn into ‘fights.’
“What Virgil and I spoke about is going back to boxing, smart boxing. I think that is what Virgil Hunter has to teach me, to stick to a game plan. At times in the past, I went out there and I saw red and went all-out, forgetting the game plan. I think Virgil will get me to use all of my speed, ability and skill at the right times.”
Khan is convinced he will be able to show his true form against the unbeaten American Molina, although he acknowledges he has to prove himself again after his recent defeats.
“Molina is an undefeated fighter and all undefeated fighters are dangerous fighters. This fight is a step up for him and, in a way, it’s a step up for me too coming off of a loss. I have to win this fight and I have to win it in good fashion.
“I’ve seen him fight. He is very skilful, but he is beatable. I can win this fight, but I need to win convincingly. This is the time to prove myself and I will do just that on December 15.”
