Khan's first fight under Rubio ended in his first defeat in 19 bouts

Amir Khan is planning to remain with his new trainer Jorge Rubio despite the Cuban's fateful suggestion of Breidis Prescott as an opponent.

Khan, 21, linked up with Rubio in July and Prescott was seen as a stepping stone towards a world title fight.

The Colombian went into Saturday's fight with 17 knockouts from 19 fights and knocked Khan out in 54 seconds.

But Khan told BBC Sport: "Rubio's a brilliant coach, I'll show what I've learnt in the next few fights."

Khan split with former coach Oliver Harrison in May after the 47-year-old had guided the 2004 Olympic silver medallist through his first 19 wins as a professional.

Dean Powell prepared Khan for his win again Michael Gomez before the Bolton fighter hired Rubio, a former coach of the Cuban national amateur squad.

"I didn't really get the chance to get into the fight and to show what I've learnt from Rubio," Khan, who relinquished his WBO intercontinental lightweight title, told BBC Radio 5 Live.

"What happened could have happened to anyone. It could have been Prescott on the other end of that.

"I've learnt a lot from Rubio in the last 8-10 weeks."

Frank Warren shouldered the blame for Khan's defeat but the lightweight also insists he is not on the lookout for a new promoter.

"I'm going to leave it with Frank, Frank's the right match-maker," said Khan.

"I'm going to leave it with him and hopefully I'll come back from this defeat stronger and I'll prove all the critics out there wrong."

Despite the setback, Khan is determined to come back stronger and build his way towards a world title fight and he is eyeing a comeback bout before the end of 2008.

"I don't want to stay out of it too long, I want to get back into it straight away," he said.

"I'm still young, I'm still hungry and I just want to get in there and get another fight out the way this year and from there go on to bigger things.

"I've still got my ambition to become a world champion and that's what I'm aiming for."
