BREIDIS Prescott has vowed to knockout Amir Khan in four rounds.

The unbeaten Columbian has an impressive record of 17 knockouts in his 19 professional wins.

Big-hitting Prescott takes on the Bolton ace for his WBO Intercontinental lightweight crown in Manchester tomorrow night.

And the explosive 25-year-old does not intend to hang around.

“I’m prepared to beat him, hopefully in four rounds, and let’s see how it goes,” said Prescott, who demonstrated his power by breaking one of his trainer’s fingers in the build up to the fight.

But Khan remains unconcerned by the bigger and taller South American’s punching prowess – and thinks his come-forward style will suit him perfectly.

“He may have a good record but who has he fought? He’s never fought anyone like Amir Khan,” he said.

“He’s made for my style. It’s going to be a tough fight but I know I’m the better fighter. I’m going to just go in there and do what I normally do and that’s win.

“Every fight’s big fight for me, as everyone who comes into the ring with me is trying to make a name for themselves by beating Amir Khan but I’m ready for that.”

But the Olympic silver medalist is still predicting his toughest test so far of his 18-fight career.

He added: “It’s very risky. It’s a big step for me fighting an opponent with a big knockout percentage, he’s undefeated just like myself and it’s a 50-50 fight. It’s going to be a tough fight on the night and the best man’s going to win. I want to be a world champion at a young age so these are the fights I need.

“He’s going to be strong – he’s got the height and reach advantage, but I’ve done my homework and I know how to deal with that.

“I’ve got my gameplan and I’m going to stick to that.”
