Eddie Hearn, promoter for IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua, says there is no doubt that his boxer is actively working on a strategy to defeat WBC champion Tyson Fury.
The two sides are close to finalizing an agreement for a full division unification - with the contest to take place on a target date in June. The location is unknown, with several locations interested in securing the big event.
Hearn feels there are a lot of similarities between Joshua and Mexican superstar Saul "Canelo" Alvarez.
The outspoken promoter is currently working with Canelo under a two-fight contract.
"I see similarities, not in the ring, between him and Canelo," Hearn told Sky Sports.
"Two guys who came from nothing, who have built their legacies, who have the same hunger now as when they first walked into a gym. That's what makes a winner. Joshua is constantly trying to evolve. When you walk into Canelo's dressing room after a fight he is talking to [his trainer] Eddy Reynoso about how he can improve."
Most observers view the unbeaten Fury as the favorite to beat Joshua.
Hearn obviously disagrees, and expects his boxer to do a real job on the 'Gypsy King.'
"He is so focused. Although he'd tell you that he's training just to improve as a fighter, I know that all he's thinking about is Fury," Hearn said.
"He's working on the plan to beat this guy and become undisputed. I love the work he's doing, the improvements he's making, the mind-set. He has the mind-set of a winner, of a champion. Fury is a fantastic fighter but AJ will do a job on him.
"The preparation starts now. Don't think Fury isn't doing the same. He knows. This may be the biggest fight of all time."
