Boxing legend Mike Tyson is helping former UFC heavyweight champion Francis Ngannou ahead of his fight with Tyson Fury – and he says his man has a major chance.

Few people alive know more about heavyweight power punching than Iron Mike, but not everyone is totally convinced that the Cameroonian-French 37-year-old has got what it takes to mix it with Tyson Fury.

The Briton, who holds the WBC heavyweight world title, had been criticised in boxing circles for taking on the exhibition match rather than fighting the IBF, WBO, IBO and WBC champion. However, a fight between Fury and Usyk is also now on the cards, for either December or January.

Undefeated Fury will be an overwhelming favourite against the 6ft 4in tall, 20st fighter, whose narrative arc is extraordinary. From a small village in Cameroon, Ngannou worked in a sand quarry from the age of 10, later travelled on foot across the Sahara and then boarded a raft across the Strait of Gibraltar. The 36-year-old ended up being homeless on the streets of Paris, before walking into a gym, which changed his life. 

The fight will be under standard boxing rules, 10 rounds and three judges will settle the fight if necessary. Check out this viral video of the contest.
