Cruiserweight contender Richard Riakporhe has been training alongside with former two-time heavyweight champion Anthony Joshua.
The British superstar is getting prepared for his upcoming rematch with WBO, IBF, IBO, WBA heavyweight champion Oleksandr Usyk, which takes place on August 20 in Saudi Arabia.
Joshua will attempt to bounce back after losing a twelve round decision to Usyk last September at Tottenham Hotspur Stadium.
Riakporhe believes Joshua has a newfound hunger and intensity as the second encounter draws closer.
"I can't give away the game plan because I would get slaughtered but one thing I will tell you, the intensity, the intention behind his shots when he throws, the hunger, with what he's achieved so far, coming back into the gym day in and day out," Riakporhe said to Sky Sports.
"A lot of people would not be able to do that if they had achieved what Anthony Joshua has achieved so far. He's hungry. He wants to create a legacy for himself. I can see in his eyes, I can see in his body language. I message him, he's up at 6am sending me videos. I'm sending him videos too, studying, studying and studying some more."
Former cruiserweight champion Johnny Nelson is ruling out the scenario of Joshua making the proper adjustments to become a three time heavyweight champion.
"This is not an impossible ask," Nelson said. "It's very possible. AJ's got to go in there with the right mindset, the right game plan. This is a fight he can win and become a three-time heavyweight champion of the world.
"Look at the last fight. Look at the state of Usyk when he came out. Usyk looked like he'd been hit by a bus even though he won and AJ lost. AJ now has to go in and do what he does. Go in and fight his fight. So let's see if there's a difference. Use that height, use that range. Use that ruggedness about him. If he uses that, I cannot see him losing. Yes, the hullabaloo is there about Oleksandr Usyk but he is beatable. It can be done."
