Fury defends the WBA, WBO and The Ring Magazine belts against Ukrainian Klitschko in Manchester, two weeks on Saturday.

"I think it's big enough as it is," explained Joshua. "That's why I'm not trying to wait around. Whenever he's ready. As soon as he's ready, we'll get it on. It's still a massive fight if he doesn't hold any belts, 100 per cent it is. The belts make it unbelievable for a unification, but it's still a big fight for the UK. A unification match makes it a global thing."

Joshua, who has 16 knockouts from sixteen fights, rates himself at 70 per cent of the finished product at present. "I just think it's still the beginning. I feel I'm improving all the time. This is just the start. The cake hasn't been put in the oven yet. I'm probably at 70 per cent. There's 30 per cent more of me to come. 100 per cent is unstoppable. Nothing's gone wrong so far. I'm not going to change much at the moment."
