“You can’t train what we have. It’s a gift from the ancestors,” John Fury says.

So, with Tyson at 37 and in the twilight of his career, some might be thinking that the Fury era will soon be at an end.

Instead, it is far more likely that the spotlight will shift from Tyson to his cluster of cousins, brothers, sons and nephews.

Boxing is not just a hobby for the Furys. It is the family business, inherited by one generation after the next.

Tyson’s son Prince may only be 14 but is already standing at 6ft 1in. The early signs are that he possesses that freakish reach and the twitchy, unorthodox movement that made his father a two-time world champion. His cousin John Boy, two years older, is also starting to fill out his considerable frame.

A debate about whether nature or nurture is more important in developing fighters is redundant in this instance. As outlined, the Fury family have pedigree in their blood, but the next generation are also now benefitting from an elite environment, too.

Prince and John Boy are absorbing every second of overseas training camps and are being drilled by Robert “Sifu” McInnes. They are both insistent that boxing is their future.
