Anthony Joshua has power beyond measure but would struggle against David Haye, says Dereck Chisora's trainer Don Charles.
The IBF world heavyweight champion (17-0-KO17) has risen to the top of the sport with relative serenity but Charles, who trained Joshua when his amateur career was in its infancy, believes the ringcraft of Haye (28-2-KO26) would be decisive if the Londoners clashed today.
Charles told Sky Sports: "I had the privilege of training Anthony at a very early stage in his career, as an amateur, and his power is immeasurable. It's truly immeasurable.
"Joshua is a very determined young man, he's learned to have that patience. Joshua is top of the tree, because he's the current world champion.
"That build is not that of a fighter, but apart from Dillian Whyte he hasn't been in a gruelling fight. You can't take that power, but you can nullify it.
"He is better than Tyson Fury. However, right now if he was to fight Haye, I'd pick David Haye, if you were to put them in the ring together tomorrow. Haye is very clever. His ring IQ is very high. The trick is to get someone to miss.
"Haye is a master at making people miss. He was making Klitschko miss miserably. He lost because he was too negative. Had he jumped on Wladimir from round six he'd have beaten him."
Joshua is yet to name an opponent for the second defence of his crown having ground down maiden challenger Dominic Breazeale for a seventh-round stoppage in June.
