ANTHONY JOSHUA admits Kevin Johnson will provide him with the toughest test of his career tonight. Joshua has knocked out every one of his opponents in a 12-fight run in the paid ranks.

But the Olympic champion knows it won’t be easy to finish off Johnson inside the distance at London’s O2 Arena.

They meet for the WBC International heavyweight belt and American Johnson is brimming with confidence.

The 35-year-old has lost six of his 36 fights, but, significantly, he has never been stopped.

Joshua, 25, acknowledged that he faces a formidable and experienced foe, saying: “He’s definitely very confident.

“He has been in with incredible opponents and been able to survive – not beaten them but been able to survive.”

Johnson has gone the distance with Vitali Klitschko, Dereck Chisora and Tyson Fury, and Joshua said: “I think that’s where he gets his confidence.

“I’m new to the professional game and he’s been in it for many years. I believe this fight is all about me and how I approach it.

“It’s simple things, like understanding the kind of shots to fire at Kevin that will break him down. He may be a name on paper but I’ve had harder fights and I’ll be able to deal with him in good fashion.”

Not surprisingly, the bruiser from Atlanta begs to differ.

Trash-talking Johnson said: “Once this dude is out the way, I’m going to show you the future of the heavyweight division is right here with me.

“I was at about 60 perpent for Klitschko, this time I’m 100 percent. I’m going to be explosive!”

The O2 Arena bill is topped by Sheffield’s Kell Brook defending his IBF world welterweight title against Birmingham’s Frankie Gavin.

An action-packed card also has Scotty Cardle and Craig Evans battling it out for the vacant British lightweight title.

Unbeaten Newport fighter Evans is aiming to prove the bookies wrong in a fight where Cardle is odds-on favourite.

Evans said: “Cardle is a good fighter, but I feel I am being a bit underestimated. I don’t think he has met anybody of my calibre.”
