Robert Garcia, trainer of two-time heavyweight champion Anthony Joshua, explains that his boxer is entering next month's rematch with Oleksandr Usyk with a brand new mindset.

When they collided last September at Tottenham Hotspur Stadium, Usyk outboxed Joshua over twelve rounds to capture the IBF, IBO, WBA, WBO heavyweight titles.

The rematch takes place on August 20 in Saudi Arabia.

Garcia spoke to Joshua about the first encounter and felt the British star had the wrong gameplan from the start.

"You know what? I think he wasn’t thinking and prepared to win the fight. From what he told me, he was just thinking of going all 12 rounds. He never thought, ‘I got to win the fight. I just need to go 12 rounds.’ So that makes a big difference," Garcia told Seconds Out.

"Now, he’s thinking of winning and thinking of hurting somebody. That’s the most important thing. He’s got to be confident with his team."

Garcia replaced career-long trainer Robert McCracken as the head coach of Joshua's corner.

He's training him to take the fight to Usyk.

"Week by week, we see a lot of improvement in Anthony Joshua. He’s going to get better and better, so by the time the fight comes, he’s going to be 100 percent ready," Garcia said.

"He’s got to be with a team that wants him to win, wants him to perform, and wants him to be a little bit tougher. I think that’s what I bring in. Me and Angel Fernandez are pushing him to be aggressive, to be a mean guy in the ring, to hurt anyone in front of him. He’s been doing that lately, and I’m very happy and pleased with how things are going."
