The Watford pro, who only started boxing at the age of 18, gave notice of his intentions in the sport by claiming gold at the London 2012 olympics – and hasn’t looked back.

In the capital, he dethroned the American with a right hand that had the referee stopping it when he hit the canvas for the second time, to become the 6th British boxer to hold a heavyweight title.

“I’m only quarter of the way there. There’s still a lot of work to be done. I’ve done two rounds, so I’ll go to the changing rooms and work on the pads,” said Joshua, who’s previous fight went 7 rounds against fellow Brit, Dillian Whyte.

The former holder acknowledged  his opponent after. “He’s not difficult to fight. He’s a great fighter, I want to say that, it was just that his right hand was fast, I didn’t see the right. He’s got good speed.”

The new IBF heavyweight champion will soon be eyeing the other belts; WBA and WBO, currently held by the former IBF holder – Tyson Fury.

Fury, who lost the title – rather than defend it, when he decided on a second fight with Wladimir Klitschko this summer – who he beat last year, could be on the verge of a British heavyweight unification fight with Joshua.

But not before Joshua could line up another British head-to-head with former champion, David Haye, who had a comeback victory and fights again in May.
