Former world champion Amir Khan is confident ahead of Carlos Molina bout in Los Angeles

Amir Khan has pledged to reign in his killer instinct and be more patient as he aims to get back to winning ways against Carlos Molina on Saturday.

The Bolton fighter has lost his last two fights largely because he got himself into brawls when he did not need to.

Lamont Peterson dragged him into the trenches a year ago to come out on top while Danny Garcia caught him off guard with a left hook in July en route to a fourth-round stoppage win.

Khan has sought to rectify that by switching trainers from Freddie Roach to Virgil Hunter and expects the move to pay dividends.

"Beat a fighter up, make him quit - that's probably better than knocking a fighter out" - Amir Khan

"One thing I've learned though is not to go for those knockouts," he said.

"They'll come themselves. Beat a fighter up, make him quit - that's probably better than knocking a fighter out because it's making him submit.

"With the sparring I've had I've not been focusing on knocking an opponent out, it's been about beating him up until he himself falls or gives up."
