So the fans don't give him any chance and his manager thinks the fight is too soon in his career. But it is all about taking your opportunities when you can. And Gary Cornish says he is going to do just that.

So not many people are tipping the giant Scot to win this one. Cornish even had tosweet talk his manager Tommy Gilmourinto making the fight.

"If he had listened to me, I would like to have seen it happening in 2016," said Gilmour. 

"But he talked me into the fight as he said he wanted it because he wants to be the first to beat Anthony Joshua.

"It is certainly Joshua's hardest challenge to date."
