I don't think it will be an easy fight for Joshua by any stretch. I think he'll win, but I'm not sure you could say he's got a better boxing brain and patience than Klitchko .
Good to see some respect from both of them though, for each other and for boxing...compare that to the WWE style of Chisora, Haye etc
Its clear that Klitchko has vastly more experience and is a very intelligent fighter, but if you no longer have the speed, power or endurance its going to be very hard to make that count.
Should be an interesting fight, I feel its more of a final payday for Vlad than a genuine attempt to regain his belts.
The respect between him and AJ was great, although both fighters are not a fan of trash talking so it was never going to get like that.
