Former cruiserweight champion Tony Bellew has tabbed Anthony Joshua as the best fighter in the heavyweight division.

Joshua is scheduled to defend his IBF, IBO, WBA, WBO world titles against Jarrell Miller on June 1 at Madison Square Garden in New York City.

Bellew saw action in the heavyweight division in 2017 and 2018, when he won back to back fights, by knockout, against David Haye.

There were talks of heavyweight fights against Tyson Fury, Dillian Whyte and Joseph Parker - but none of them ever came off.

After returning to cruiserweight and suffering a knockout loss to Oleksandr Usyk last fall, Bellew retired from the sport.

There are three fighters widely viewed as the top tier men at heavyweight - Joshua, WBC heavyweight champion Deontay Wilder and linear champion Tsyon Fury.

Bellew views Joshua as the top man above the rest.

“AJ is the best heavyweight in the world. Physically, athletically, everything. He is fast and explosive. He is the perfect role model. To look at where he has come from to where he is now is incredible," Bellew said to Give Me Sport.

On the other hand, Bellew does not have the highest opinion of Wilder's technical abilities.

He views Wilder as being the worst champion, at least on a technical level, in the history of the sport. But he does have a high regard for Wilder's one-punch power with the right hand.

"The worst, least technically gifted heavyweight champion ever,” started Bellew.

“Deontay Wilder is the worst heavyweight champion of all time. Technically, I don’t think there has ever been a worse champion.

"This man can’t throw a proper combination. This man hits the lights when he throws a right hand. He is ultimately a one trick pony. Don’t get me wrong, it’s a fantastic trick, but it is just one. He has been exposed at the top level.”
