KAMARU USMAN'S manager reckons the UFC champion would knock out 'COWARD' Canelo Alvarez in three rounds.
Usman has long called out the Mexican boxing superstar, who is the sport's current pound-for-pound best.
But Ali Abdelaziz, who manages the UFC welterweight king, blasted Canelo for refusing to fight in the cage.
Abdelaziz told : “I know he didn’t want to fight Jake Paul; he didn’t want to fight Logan Paul.
“He said I’m the pound-for-pound king in MMA, I want to fight the pound-for-pound coward in boxing because I think all these boxers are cowards because none of them want to come to MMA.
“They all want to come to boxing, but at the end of the day, in a street fight, who’s the baddest man on the planet?
