I think Joshua would make short work of Tyson Fury. He's miles better, much stronger, quicker, more intelligent, the guy punches so hard that no one will be able to stand up to him. His combination of power and speed is absolutely lethal. The only one that might give him a tough time is Deonty Wilder
I remember the days when people were saying no one could stand up to Mike Tyson's punches.
Joshua reminds me of Frank Bruno, with a bit more boxing skills.
Fury, I think would outbox him and frustrate him, with the same tactics he used against Wlad.
Big, muscular fighters who have not taken their prey out inside 6 rounds, normally run out of gas- see Ali v Foreman, rumble in the jungle.
