Former world heavyweight champion David Haye insists he is in the “best shape of his life” after changing his training camp routine ahead of his fight with Tony Bellew.

Haye landed back in Britain earlier this week after doing the majority of his training camp in Miami.

The former WBA heavyweight champion will now add some finishing touches to his training before taking on Bellew at the 02 Arena in London on March 4.

Bellew has criticised Haye’s training methods but the Londoner insists his new regime has got him in the best shape he’s ever been in.

He has worked with new trainer Shane McGuigan for the last few weeks and the 36-year-old expects to be too big and strong for his rival, with Bellew, the WBC cruiserweight champion, stepping up a weight division.

He told Sky Sports News HQ: “It’s all about getting a good balance in life and I think I have found the perfect balance for me at 36 years old.

My body is in the best condition it has ever been in and I am enjoying life, enjoying every day. “I look back at what I used to do.

At the time it felt very right, and it worked as I won multiple world titles, but the way I am doing things at the moment it could have been a lot easier.

Training camps could have been a lot happier and I could have had fonder memories.” Haye is the heavy favourite to beat Bellew next month and he can be backed at 10.00 to win inside the first round.
