Bellew: Kell Brook Can Beat Errol Spence, But it Won't Be Easy

Former WBC cruiserweight champion Tony Bellew knows what it's like to pull off a major upset.

Back in March, he moved up to the heavyweight division to stop heavily favored David Haye in eleven rounds.

On May 27th, Bellew's good friend, IBF welterweight champion Kell Brook (36-1, 25 KOs), will defend his belt as the underdog when he takes on unbeaten Errol Spence (21-0, 18 KOs) at Bramall Lane in Sheffield.

This will be Brook's first bout since last September, when he moved up by two weight divisions and was stopped in five rounds by IBF, IBO, WBC, WBA middleweight king Gennady "GGG" Golovkin.

There are many who feel Brook will be the bigger man in the contest - but Bellew disagrees.

"I actually don't think Kell will be the bigger man against Spence Jr. I saw them face-to-face weeks ago and Spence Jr looked bigger. Spence Jr is a good sized welterweight, he's very similar to Kell. As long as Spence Jr isn't drastically cutting weight, he should keep his size," Bellew told Sky Sports.

I'd like to see Kell have two, at the most, more fights at welterweight. But I've been down this road myself against Adonis Stevenson. Nobody wants to hear that you're weight-drained - if you're weight-drained, don't fight. You can't lose, then say it's because of the weight. Kell can do it but it's going to be tough. Spence Jr is younger and fresher but he hasn't fought the same calibre of opponent as Kell."

BoxingScene.com posted training camp photos of Brook on Wednesday and the boxer was shredded to the max.

"The weight could be an issue but I don't think it will be. He wouldn't have been stupid enough to take on the task if it were a problem. Kell looks in fantastic shape, but to be honest, he looks in shape when he's 12 stone. Genetically, he's a beast. I don't go on appearances - I'm Mr. Soft, I look like I've never trained a day in my life. Some guys are just more genetically gifted than others - aesthetically Kell looks absolutely perfect," Bellew said.
