According to Eddie Hearn, should Kell Brook emerge victorious against Gennady Golovkin, he should be considered the best in the world.
The British boxer went up two weight divisions to challenge the undefeated Kazakh for middleweight glory.
Since the retirement of Mayweather, Golovkin who is undefeated in 35 fights and has 32KOs is considered the best pound-for-pound boxer.
Brook is also yet to suffer a defeat in 36 fights and his promoter Hearn hopes ‘The Special One’ can become a worldwide star by toppling ‘GGG’.
“That’s why he’s taking this fight. The gamble of becoming the No 1 fighter in world, pound-for-pound,” Hearn told Sky Sports.
“Golovkin is the No 1 pound-for-pound fighter in the world. Some agree some don’t. The majority agree. Therefore if Kell beats him, he’s No 1 pound-for-pound fighter in the world.
“That’s why we’re taking this fight, to make that step, to become that global star. To become a global star, you’ve got to take risks.
“You can’t just wake-up in the morning, beat some bloke who is 26-5 and become the greatest fighter in the world. You’ve got to go and do something out of the ordinary and that is beating Gennady Golovkin.”
“I don’t think there is a welterweight that would beat Kell Brook. But now he’s moving up to middleweight where I think he will be a better fighter.
“If he wins, it’s huge. That’s what the gamble is, that’s what you’re playing for. You’re not playing for a good win, you’re playing to be the best and cement your legacy in the sport.”
