Mayweather: Spence late show can beat Brook
Floyd Mayweather believes Errol Spence Jr will defeat IBF welterweight champion Kell Brook on Saturday if he can take him to the later rounds.
The 40-year-old five-division world champion, who retired in 2015 undefeated in 49 professional bouts, has given his verdict looking ahead to the eagerly-awaited head-to-head at Sheffield United's Bramall Lane ground.
Errol is a hell of a fighter, we sparred and he gave me good work, If he can fight in the later rounds I lean towards him.Floyd Mayweather
The 30-year-old Brook will fulfil his dream of fighting at the home of the football club he supports as he drops back to the 147lbs division to defend his IBF crown having moved up two weight divisions to take on middleweight champion Gennady Golovkin last time out.
Despite his fifth round defeat in that fight, which subsequently ended his unbeaten record, Brook is confident that he will have enough to negotiate the test Spence Jr will bring to the ring.
However, Mayweather knows all about Spence Jr's credentials having sparred with the unbeaten southpaw in 2013 ahead of the defence of his WBC welterweight title against Robert Guerrero and he feels his fellow American can come away with the belt, especially if he can take Brook deep into the 12 rounds.
"Errol is a hell of a fighter, we sparred and he gave me good work," Mayweather told Sky Sports.
"If he can fight in the later rounds I lean towards him.
"I know your guy Brook can fight and boxed real good against Triple G, so we've got a great fight on our hands."
Brook is 7/4 to win the fight and defend his IBF strap, while Spence Jr can be backed at 10/21 to win and the draw is 20/1.
