Former two division world champion David Haye believes countryman Anthony Joshua could very well retire if he suffers another defeat in his upcoming rematch with Oleksandr Usyk.

Back in September at Tottenham Hotspur Stadium in the UK, Usyk outboxed Joshua over twelve rounds to capture the IBF, IBO, WBA, WBO heavyweight titles. The outcome marked the second defeat of Joshua's career.

The rematch takes place on August 20 in Saudi Arabia.

“If he doesn’t win, I am not sure he wants to be in a sport where he knows he is not the best. He got out-hustled by someone he knows he can beat and if - he does everything right and Usyk still beats him - I don’t know if there is anything else for him to do in the sport," Haye said.

“He is such a winner that I don’t know what he does next, if he loses again. He believes he has all the physical abilities to beat Usyk, so do I, so with the right plan he can get the victory.”

Haye expects Joshua to make adjustments and look better in the second meeting.

Joshua parted ways with longtime trainer Robert McCracken and secured the services of veteran coach Robert Garcia.

“I think his performance this time around can’t be worst than in the first fight. In terms of tactics and gameplan, that was the worst, so I am sure Robert Garcia won’t do that again," Haye said.

“Change is good; different methods face and voice. In the first fight, whoever was saying what and whoever came up with the plan is irrelevant, he just has to win this fight to get back on top of the world.”
