Two British boxers are coming up on the biggest fights of their respective careers. Welterweight champion Kell Brook will move up in weight and challenge middleweight Gennady Golovkin of Kazakhstan on Sept. 10 in England (on HBO). A week later, on Sept. 17, Liam Smith will be defending his junior middleweight title against Canelo Alvarez of Mexico at AT&T Stadium in Arlington, Texas (on HBO pay-per-view).

Smith (23-0-1, 13 KOs) believes he’s the Brit with the best chance to emerge victorious.

“Yes, 100 percent,” Smith said Thursday during a conference call. “I like my chances because I’m 100 percent confident I’m going to win this fight, and Canelo’s the favorite to win the fight. And I’ll be rooting for Kell Brook, but I think it’s a step too far for him. But I don’t think it’s a step too far for myself.”
