Anthony Joshua produced a withering assessment of rival Deontay Wilder by claiming the 'Bronze Bomber' is 'not an elite level fighter'.
Wilder is busy preparing to face Tyson Fury in a trilogy fight after a judged ruled on the legitimacy at his right to a rematch following his brutal defeat.
The American is full of confidence in winning back his WBC heavyweight belt and has talked up his next move, chief among them being to fight Joshua for the undisputed title.

But Joshua, who now looks set to face WBO mandatory Oleksandr Usyk with a Battle of Britain fight against Fury temporarily shelved, has suggested there are levels to greatness - and Wilder is not on his level.
Joshua told Sky Sports: 'I'm an elite level fighter, not one of the tomato cans he's knocked out.
'He better watch what he's saying because when the day comes for me and him, I know what I'm capable of doing.
'He ain't an elite level fighter.'
Joshua continued his takedown of the Alabama fighter by going on to add that Wilder's explosive right hand is his only 'weapon' and no heavyweight champion can 'go to war' with just one in his armoury.
