Amir Khan knocks out Phil lo Greco in 40 seconds; targets Kell Brook

Khan had Lo Greco on the canvas after only 13 seconds

Amir Khan's return to the ring lasted less than a minute as the Briton knocked out Phil lo Greco in only 40 seconds in Liverpool.

Khan, fighting for the first time in two years, first dropped Canada's Lo Greco after just 13 seconds with a blazing left-right combination.

And he delivered the coup de grace with a flurry of thunderous body shots soon after.

"I was a little nervous, but I am back with a big bang," Khan, 31, said.

"I want to become a world champion this year or next year."

Khan's focus after the light middleweight bout turned to Kell Brook, who was ringside, with the Bolton fighter saying Brook had been "living off his name".

Former light-welterweight world champion Khan had not fought since his knockout defeat by Saul 'Canelo' Alvarez in Las Vegas in 2016, while his previous bout in Britain ended in a points victory over Julio Diaz in Sheffield five years ago.

"I have been out the ring for two years but I was still in the gym working hard, I have never taken a day off. I wanted to prove a point coming back," he added.

Amir Khan and Kell Brook exchanged words after the fight

'I'm not a fighter to run away'

Khan and Sheffield fighter Brook, 31, have long been touted for a potential grudge match, and are now both signed to promoter Eddie Hearn's Matchroom Boxing.

"That fight is something I am not rushing and not running away from," Khan added.

"I will fight Kell Brook and beat Kell Brook. Kell Brook has been living off my name for a long time. I am a stronger fighter, a better fighter.

"I'm not a fighter to run away."

Brook responded by telling Khan he would make him "see stars" - a reference to Khan's stint last year in TV show I'm A Celebrity... Get Me Out Of Here!

"Amir, all the fans want the fight, I want the fight," Brook said.

"He can go in the jungle and chase stars but when he gets in there with me, I'll make him see stars."

Hearn said he hopes the pair deliver a fight "the British public wants".

"Kell Brook doesn't like Amir Khan. Amir Khan doesn't like Kell Brook. This fight should have happened 12 months ago, two years ago. We've still got time. Let's not regret it," he said.
