Retired former five division world champion Floyd Mayweather Jr. (49-0, 26KOs) is picking Saul 'Canelo' Alvarez (48-1-1, 34KOs) to knock Gennady 'GGG' Golovkin (36-0, 33KOs) out - when the two fighters meet each other in the ring.

There are ongoing discussions for Golovkin and Canelo to face each other next September.

Golovkin was in action last month, when he traveled over to the UK and stopped Kell Brook to retain the WBA/WBC/IBF/IBO middleweight titles. Canelo also fought last month, when he packed the AT&T Stadium to score a knockout win over Liam Smith to capture the WBO junior middleweight title.

Mayweather handed Canelo his first and only loss back in September of 2013. They met at a catch-weight of 152-pounds, with Mayweather dominating the contest.

"Canelo beats Triple G easy. Yeah he'll beat him, he stops him," Mayweather told ES News.

There are many fans and critics who believe Canelo is avoiding the fight. Some of his own fans are calling him a coward. Mayweather went through the same criticism for several years, during the stalled negotiations to finalized the Manny Pacquiao fight. That fight was finally made last May, and broke every financial record every created for boxing. Mayweather boxed his way to a twelve round unanimous decision win with few problems.

Mayweather advised Canelo to ignore the critics and do what's best for his career.

"I want to tell Canelo this. Live your life, do what makes you happy. Me as a fighter, Floyd Mayweather, for years they called me a coward. They said I was scared of Manny Pacquiao. Manny Pacquiao is a Hall of Famer. They said I was a coward, I was scared and all that do is inspire me to work harder, keep pushing myself and there is no limit to how high Canelo can go. He has a crazy fan-base," Mayweather said.
