NEW YORK, (Reuters) – Amir Khan longs for peace  after all the trash talking heaped on him by New Yorker Paul  Malignaggi, and the Briton reckons a knockout defence of his  WBA super lightweight title on Saturday would do the trick.

Khan, making his U.S. debut at Madison Square Garden, told  reporters yesterday he was happy that the war of words with  the challenger would be replaced by punches.

“I’m happy to fight him just to shut him up,” Khan, 23,  said. “I want to hurt him in the ring. I’m a nice guy, but  every time I fight I hurt my opponents, that’s just the way it  is. We can be friends afterwards if he wants to be, but I don’t  think he’ll want to be after the beating he’s going to get.”

Khan has a 22-1 record with 16 wins within the distance.

The 29-year-old Malignaggi, a former IBF junior  welterweight champion, is 27-3 but the quick-footed fighter  with the lightning jab has stopped only five opponents.

Malignaggi’s taunts often sting harder than his punches,  and the loquacious Brooklynite hurled a barrage of provocative  tweets at the Briton this week.

In a message posted on Twitter directed at Khan, Malignaggi  said “the strong survive in New York City, the lights shine  bright here, so hopefully (he) don’t fry under pressure.”

Khan said he preferred to let his fists do the talking.

“I want to knock him out and send out a message to the 140  pounders that I can beat them all,” he said.

The contrast between the boxers extended beyond their  boxing styles.

Khan was dressed smartly for the Garden news conference in  colour-coordinated gray slacks, gray shoes, gray vest and a blue  dress shirt. Malignaggi wore an oversized tee shirt, a black  New York Yankees cap turned to the side and torn blue jeans.

The New Yorker, who vacated his title to fight Briton Ricky  Hatton in 2008 for the IBO junior welterweight title and was  stopped in the 11th round, avoided the pre-fight build-up to  focus on training for what he called a “redemption” fight.

“This is redemption right here. This is what I was waiting  for — the chance to beat a champion. Everybody says Khan is so  great, is the future of boxing,” said Malignaggi.

“His manager said he wanted to come to the U.S. and fight  the toughest competition. You know what they say bro, be  careful what you wish for.”
