New York: Britain's WBA super lightweight champion Amir "King" Khan made a smashing US debut at Madison Square Garden, pummelling local favourite Paulie Malignaggi before switching his sights to bigger things.

Having stopped former champion Malignaggi in the 11th round on Saturday to retain his crown, Khan said he wanted to reign supreme in the 140-pound division and give Muslims something to cheer about in boxing.

"I have made my debut here, I know how it feels," said Khan, whose dismantling of the New Yorker was his first bout outside of Britain.

"It's the best feeling fighting in America. It's a dream come true.

"I'd love to fight in Vegas now and have a big fight there."

Golden Boy Promotions chief Richard Schaefer said he planned to have Khan return home for a bout in July before coming back for another US fight late autumn.

Khan had a game plan in mind.

"I'd like to fight (Marcos) Maidana next," the 23-year-old Khan said about the hard-hitting Argentine.

"Let (Devon) Alexander fight Tim Bradley," he said of the Americans who hold the WBC, WBO and IBF titles.

"And the winners fight just to prove who's best in the division.

"I'm not leaving 140 pounds until I unify the title. Until I'm number one I'm not going to leave this division."

Khan outclassed the quick Malignaggi in front of 4,500 fight fans, beating the Brooklynite at his own game.

He used his speed to beat the challenger to the punch and his superior power helped him win every round of the judges' scorecards before the referee halted the bout.

Khan had to move his training camp to Vancouver after he had difficulty as a Briton of Pakistani descent securing a US visa.
