David Haye has emphatically rejected Tony Bellew's criticism of his training camp, claiming he could win their upcoming bout inside one round even if he was in the worst shape of his career.
Haye will take on Bellew, who is stepping up from cruiserweight to fight the former WBA heavyweight champion, at the O2 Arena on March 4.
The two have traded verbal volleys on a regular basis since Bellew's tirade at Haye after the Liverpudlian retained his WBC cruiserweight belt against BJ Flores back in October.
A media conference in November saw the pair almost come to blows and Bellew has questioned the intensity of Haye's Miami training camp and been critical of the time the Londoner has spent with celebrity friends in Florida.
But Haye has now hit back, telling Sky Sports News: "I could turn up to this fight in the worst condition I've ever been in, and still knock him out inside one round.
"But I'm actually happy training. In the past if I had this fight, I might not have done much training for it. But because I've come here, I want to train.
"I wake up in the morning and feel good, I want to push my lungs, I want to go for a swim, I want to do some sprints, hit the bag for an hour. It feels good.
"So he's definitely got me at the wrong time in my career. He probably thinks he's got me at the right time, at the ripe old age of 36.
"But if you look at my career, I don't have many miles on the clock. I haven't been beaten up."
