Oleksandr Usyk vs Anthony Joshua 2: Carl Froch claims AJ needs 'a brain transplant' to beat Usyk

Anthony Joshua needs ‘a brain transplant’ to beat Oleksandr Usyk, according to Carl Froch.

The British superstar will rematch the Ukrainian in Saudi Arabia on August 20.

Joshua’s second meeting with Ukraine’s unified heavyweight world champion will see him bid to avenge the second loss of his professional career, which he suffered at the Tottenham Hotspur Stadium last September.

AJ has replaced former trainer Rob McCracken with new coach Robert Garcia in preparation for arguably the most important fight of his career, of which many argue he will be remembered for for the rest of eternity.

But Froch doesn’t believe he has made the right decision as he insists he should have stuck with McCracken instead.

“He’s made some big changes, AJ,” Froch told Betfred.

“He’s changed his coach which I’m against because I’m biased because I was with Rob McCracken for my entire career.

“I lost two fights and stuck with him and I wouldn’t blame Rob McCracken for that. AJ stuck something on Rob McCracken’s shoulders and thought ‘ok I need a change’. Sometimes a change is good and hopefully this change for AJ will allow him to get his mind back.

“He’s got all the bigger physical attributes. He’s bigger, he’s taller, heavier, stronger, punches harder and if he leans on his opponent then it will be hard work for Usyk. I was quite a nervous amateur and if your mind isn’t right and you don’t believe in yourself then you’ve got a whole mountain to climb.

“When you’re negative and you feel like you can’t beat somebody then it’s very difficult to start beating them. I think Anthony Joshua hasn’t had belief ever since the Andy Ruiz loss.”

Froch, 44, retired from boxing after beating George Groves in 2014.

The Englishman won 33 out of his 35
