Carl Froch: Anthony Joshua will need a 'brain transplant' to beat Oleksansr Usyk

Anthony Joshua is promising a better performance and believes he will knock out Oleksandr Usyk this time.

The Brit has made changes ahead of the August 20 clash, including his main trainer. Robert Garcia will replace Rob McCracken and work alongside Angel Fernandez.

Froch told Betfred's Lightweight Boxing Show: "Sometimes a change is good, but for Anthony Joshua to beat Oleksandr Usyk, he needs a brain transplant. He's got all the physical attributes but I just don't think he can beat him."

Froch told iFL TV in another interview: 'I think it's going to be difficult for Joshua to beat Usyk in this rematch; it's going to be very difficult unless he changes his train of thought and his mindset.
