Eddie Hearn believes that Anthony Joshua needs to make changes ahead of his rematch with Oleksandr Usyk.
Usyk won the WBA, WBO and IBF belts from the Briton at the end of September with a clinical and controlled technical display.
There is a rematch due for 2022, but Usyk is now considered the comfortable favourite, such was his superiority in London.
Speaking on DAZN, Hearn answered questions about Joshua, and his recent trip across America to visit gyms.
“Everyone keeps saying to me, ‘Who do you think is the best trainer for AJ?’” Hearn began.
“I said it’s just the person he believes in, he feels comfortable with, and can sit him on the stool and change the direction of a fight at the right time. Rob McCracken is his trainer, his mentor, his adviser.”
He then explained the reasons for the trip were not as dramatic as some had assumed.
“The trip wasn’t about identifying a new trainer ,it was about learning, and new environments. I believe that he needs to change his environment.
“I believe that’s a good move for him. He’s been in Sheffield since he’s been 18, that’s 14 years, and it’s an amazing camp. But he’s God there, and in the UK. What he liked about coming over here, he could go to breakfast, he could get to the gym, and he wasn’t being mobbed all day, everyday.”
