The new beginning: Daniel Dubois on a ‘new beginning’ to become a two -time heavyweight champion

Daniel Dubois posted today and gave his rationale for leaving coach Don Charles after 18 months and said he had a “Fresh start” with his pro career. Dubois, 27, is now being trained by Tony Sims.

Dubois’s ‘Fresh Start’ rationale

Daniel mentions that he plans to make an effort to become a two -time heavyweight champion, and he needs new input from a coaching perspective.

Former IBF heavyweight champion Dubois (22-3, 21 Kos) lost its title in a round defeat against IBO, WBA, WBC and WBO champion Oleksandr Ulsyk at their Rematch on July 19 at Wembley Stadium in London.

Fans have openly criticized Dubois for abandoning Charles because they believe he uses him as the scapegoat and does not accept the responsibility for his defeat.

The coaching history

Dubois’s new coach, Tony Simms, is the fourth coach Daniel worked with during his eight -year professional career. His coaches in the past:

• Don Charles
• Shane McGuigan
• Martin Bowers

Dubois’s decision to throw a small party before re -broadcasting with USyk was guessed by fans on social media. They felt that it was a foolish step for him to treat the fight as if it were a sure victory.

Retired former heavyweight champion Lennox Lewis was also known for having many trainers. He was trained by Emanuel Steward, Pepe Correa, and Harold Knight.

Dubois’s career recovery

“I would like to thank Don Charles for the hard work he has put in me for the past 18 months. But now I feel like I need a new change, a new beginning for this next phase of my career, where I want to become a two -time heavyweight champion of the world,” Daniel Dubois to Dazn Boxing said.
