Former division king Tyson Fury has offered another scathing verdict on IBO, IBF, WBA (Super) world champion Anthony Joshua's credentials by stating he "can't box" and "you can never turn a carthorse into a racehorse".
Fury wasted no time in calling out fellow Brit Joshua after moving a step closer to a return to the ring when UK Anti-Doping (UKAD) agreed a resolution to proceedings brought against him this week.
Former heavyweight champion Fury has his sights set on a fight with Joshua, provided the British Boxing Board of Control agree to give him his licence back.
Fury has made no secret of the fact that he is not impressed with his compatriot and the 'Gypsy King' has taken another pop at the former 2012 London Olympic champion.
Asked how he feels Joshua has developed since beating Carlos Takam via a tenth round stoppage in October, Fury said: "Still the same, bit heavier, few more muscles on him, that's it really. The man can't box, he's not a boxer. He's a brawler.
"When he gets in there with someone who can box and move, he'll get beat, simple as that. When I say these things, I don't just say it because I don't like somebody or whatever, I say it because I know the truth.
"The truth of the matter is he'll get his head punched in by anyone who can box and move a little bit, simple as."
Quizzed whether Joshua can iron out his weaknesses, he added: "No, because you can never turn a carthorse into a racehorse. He ain't built for movement and speed. He's built for power.
"You can't make a power man a speed man. Without speed and movement in heavyweight boxing, you're a limited fighter. You're not going to blast through everybody, like we saw with (Carlos) Takam, at 12 days' notice."
