Fears for Anthony Joshua as Oleksandr Usyk training footage shows heavyweight rival's hench body transformation

FANS are fearing for Anthony Joshua after Oleksandr Usyk showed off his huge body transformation in fresh training footage.

The heavyweight giants collide in Saudi Arabia on August 20 for their highly-anticipated rematch.

And the pressure is on AJ to reclaim his belts after losing last year’s bout in London.

Joshua has been working hard in preparation for the epic bout.

And the winner could end up facing Tyson Fury to unify the division – should the Gypsy King come out of retirement.

However, AJ knows it will be a long and arduous battle against Usyk.

The Ukrainian was the classier fighter in the first match despite his smaller stature.

But new training footage shows Usyk has packed on more more muscle in a bid to make his punches extra powerful.

The ace also looks to have retained his lightning hand speed and quick feet.

And fans reckon that, combined with a bulkier frame, Usyk could have too much for AJ to handle again.

One said: “This guy is about to destroy Joshua and put him into retirement.”

Another declared: “Have a feeling AJ’s about to be sent to the shadow realm.”

One noted: “He’s looking big there. Bigger in fact. He’s coming for the KO I reckon.”

Another decreed: “Sheesh man, he’s looking huge. He’s 100 per cent stopping Joshua this time.”

One added: “Looking massive, starting to get comfy at heavyweight.

“Toughest fight of AJ’s career even including a Fury fight if that ever happens.”
