Amir Khan made his return on Saturday (April 21), after a nearly two-year layoff.

The 31-year-old boxing star showed that he’s still got it, when he stopped Phil Lo Greco in just 39 seconds.

The KO was the quickest of Khan’s career (32-4, 20 KOs), and came in front of fans at the Echo Arena in Liverpool.

After the fight, Khan challenged English rival Kell Brook.

“Khan is back,” Khan said afterward in the ring. “I wanted to prove a point. I trained for a 12-round fight. My hand coordination is very sharp. I saw I hurt him with the left hook and it was over. I’m back with a bang. At the moment, I’m a 147-[pound] fighter. My target is to win another world title.”

“My future holds some big fights,” Khan said. “I want to win another world title. This is where me and Eddie need to sit down with Kell’s team… I will fight and beat Kell Brook and the world knows it. Kell Brook has been living off my name for a long time. I came and signed with Matchroom, I’m the one chasing Kell.”

Khan last fought Canelo Alvarez in May 2016 and suffered a devastating 6th round KO… where he was knocked out cold. However, he did step up two weight divisions to take the fight.
