WATCH: Amir Khan knocks out Phil Lo Greco after just 40 seconds

Well, that was quick.

Amir Khan delivered an emphatic statement of intent by knocking out Phil Lo Greco after just 40 seconds. Khan hit Lo Greco with a devastating right immediately and, after a body shot, it was all over, with Khan barely breaking a sweat in what was his first fight in two years. https://twitter.com/Abuirfankhan/status/987801126014783488 After Khan destroyed Le Greco, there were immediate calls for the British boxer to face Kell Brook next. https://twitter.com/SkySportsBoxing/status/987801014320467968 What a way to make your comeback. Sensational stuff. For boxing fans, it worked out perfectly, with Khan making light work of Lo Greco just in time to switch over to the Carl Frampton fight. Following the fight, Brook said he would 'destroy' Khan. "I’ve sparred him," Brook said. "He has the fastest hands I’ve been in with. But timing beats speed. I will land that bomb on him and destroy him. I can do 147. Even if I have to cut both my legs off, I’ll get there. I want the fight. I’m dying to put him to sleep."

"I want the fight. He doesn’t want the fight, he just ran off. All the fans want the fight. I’ll make him see stars. He made 150 today, he’s been out for two years, he struggled at welterweight, why not make it at catch weight."
