‘AJ’ is four years younger than American Breazeale and possesses a slightly more impressive knockout record, leading to unfavourable odds from the bookmakers on an upset taking place at the O2 Arena.
Since turning pro on the back of Olympic success, Joshua has gone from strength to strength and seems to get better with every fight as he gains the necessary top division experience.
Fights with a rejuventated David Haye or the winner of the rematch between Tyson Fury and Wladimir Klitschko are in the pipeline for Joshua, who has stopped all sixteen of his opponents so far.

Challenger Breazeale has a fight more on his record, but one less KO to his credit and recently struggled to overcome compatriot Amir Mansour when knockout down early on in the fight.
Anyone with question marks over their chin would be ill-advised to be in the vicinity of Joshua, although the big Californian will be hoping to shock the world when the encounter goes down this weekend.
