Former five-weight world champion Floyd Mayweather has invited Anthony Joshua to train with him at the Mayweather Boxing Club in Las Vegas so the world heavyweight champion can improve one aspect of his boxing style.

Mayweather and Joshua met for the first time in London on Sunday, one day after the American oversaw his protégé Gervonta Davis notch a third round knockout win over British super featherweight Liam Walsh.

Mayweather praised Joshua for his thrilling victory over Wladimir Klitschko in April, but said he needs to improve a vital aspect of his fight game.

“You have to respect AJ,” Mayweather told Fight Hype. “He showed that he had heart [against Klitschko] but we have to bring him up to the Mayweather Boxing Club as we want to tighten that defence up until it’s real, real sharp and real, real slick.”

Though Joshua’s stock rose considerably for stopping Klitschko, the punch statistics indicated that the Londoner did not have it all his own way.

Klitschko knocked Joshua down in the sixth round and was the more accurate puncher as he landed 36.7% of his shots, compared to Joshua’s return of 30.1%.

Mayweather, on the other hand, is renowned for being the king of defence.

“I’m not trying to move his trainers out the way but there’s things we want to tweak,” Mayweather said. “You saw what we did to Tank [Gervonta Davis]… nobody knew who this kid even was. But we brought him up and now [he’s] world champion.

“Joshua’s last fight went 11 rounds but really it could have gone three. He came out and the fight was going his way but then the fight shifted and I thought, ‘oh s**t!’ But this m****r f****r got some dog in him.

“After that fight he was praising his trainers but I gotta praise [him] as it was [Joshua] in there fighting. When he was knocked down on the floor, he got up and he kept fighting.”
