The rivalry between heavyweight prospects Anthony Joshua (14-0, 14KOs) and Dillian Whyte (16-0, 13KOs) will be settled later tonight at the O2 Arena in London.

Whyte has verbally assaulted Joshua at every possible moment. They fought each other in the amateurs with Whyte coming out on top. He feels every confident of repeating the same outcome.

Joshua is built like a Greek god and looks more like a bodybuilder than a professional prizefighter.

Whyte questions whether or not Joshua's impressive physique is the product of hard work in the gym or a body constructed with the direct assistance of steroids.

"I'm not a scientist. The dude turned pro at 16.1 stone or something. Two years later he's 18 stone. He hasn't gained one percent of body fat. How does that work?  What heavyweight in history have you ever seen done that? I'm just asking you and the fans a question. How do you put on 30 pounds of muscle in three years, lean muscle, and it hasn't affected you one bit? That's impossible. No human being is capable of doing that, you can eat as much salad and eat as much nuts and meat as you want.....c'mon man," Whyte told BoxingScene.com.

When asked if he was worried about potentially facing a fighter who might be on steroids, Whyte replied:

"A lot of guys who take stuff have heart problems and he doesn't have a strong heart as it is, so I'm cool," Whyte said.

Whyte himself was hit with a two-year ban for taking an illegal substance in 2012. He tested positive for the banned stimulant Methylhexaneamine (MHA).

Whyte claimed to have unknowingly ingested the drug while taking a training supplement. The UKAD (UK Anti-Doping) believed him, concluding that his use of MHA was not intentional, but they still rejected his appeal because they said it was Whyte's duty to properly investigate the ingredients of the supplement.
