David Haye is convinced that he can make a return to the ring later this year in better shape than ever, according to Sky Sports.
The 36-year-old already once came out of a lengthy spell on the sidelines as he decided to cut his retirement short in order to face Tony Bellew in a blockbuster encounter.
However, the match ended in despair for the 'Hayemaker' as he ruptured an Achilles tendon which helped Bellew to clinch victory.
Haye forced through to the 11th round before his trainer Shane McGuigan had to throw in the towel to prevent any further damage to the injury which had first occurred in the sixth round.
But the former WBA champion has claimed that his recovery is going well and that his mental strength will allow him to make a successful return to action sooner than later.
"Boxing is a tough way to earn a living but some of us are born for this and I believe I am," Haye told Sky Sports.
"When the going gets tough I know I will fight in the ring until my very last breath and I believe most world-class fighters have that same mindset.
"My mission objective hasn't changed [becoming a world heavyweight champion]. If anything I've proved to people I genuinely want it.
"After achieving so much in my career there were a lot of question marks about whether or not I really wanted to box and I think I proved to people that I am still a fighter, that I am a warrior and that this is what I want to do.
"I'm happy with the way the surgery went, I'm happy with the physiotherapy and I'm happy with what the doctors are saying with regard to the injury and my recovery.
"Once I'm healed up before the end of the year I believe my best will be better than my effort [against Bellew] on March 4."
Despite the orders of the doctors to rest, Haye attended the BEDSAs in central London during the weekend joining Sky Sports pundit Johnny Neslon on stage to deliver a special tribute to the late Muhammad Ali.
The event recognises and celebrates sporting excellence from within Black, Asian, and Minority Ethnic (BAME) communities.
Haye added: "Muhammad Ali was my biggest inspiration so I had to come out and do this."
"Events like this are so important, particularly at grassroots level, because they really give ethnic minorities a boost, which they may not get at home.
"It makes so much difference to both those nominated and those who are following the results. It can help give them that push to get involved in sport and keep themselves healthy."
