Canelo on Golovkin: He talks a lot of sh*t about me; I hate that motherfu****

Saul 'Canelo' Alvarez refuses to let off the gas pedal regarding his hatred for Gennadiy Golovkin.

The Mexican superstar has maintained that his upcoming trilogy bout against the Kazakh is a personal one, despite their second bout having taken place nearly four years ago.

The pair will collide for a third and likely final time on September 17 at T-Mobile Arena in Las Vegas on DAZN Pay-Per-View.

Their two prior encounters also occurred at the same venue.

In 2017, their first meeting ended in a 12-round split draw, which was heavily disputed as a majority of ringside observers saw Golovkin winning a clear decision.

They were initially set to fight again in May 2018, but Canelo twice tested positive for the banned substance clenbuterol, which pushed the bout back to September of that year. Alvarez went on to win via majority decision to capture the middleweight titles, handing Golovkin the first loss of his career. Like the first bout, most ringside had Golovkin winning, although the points margin was closer than the first fight.

But unlike the first two bouts, Golovkin - who holds the IBF and WBA titles at 160 - will move up to 168 to challenge Alvarez for his undisputed championship.

Canelo claims his hostility towards Golovkin has grown over the years because of the way the latter has spoken about him since their September 2018 rematch.

"He's a f---ing assh*le," Canelo said to TMZ Sports. "He's not honest. He pretends to be a good person and be different but he's not.

"He talks a lot of sh!t about me. He'll say, 'I respect him, his career.' And, other part, 'He's an embarrassing boxer, he's embarrassing for Mexican boxing.' I hate that motherf---er because of that."

Alvarez (57-2-2, 39 KOs) is coming off the first loss of his career in nearly a decade.

On May 7, he moved up to the light heavyweight division to challenge unbeaten WBA world champion Dmitry Bivol, who upset the former pound-for-pound king and cruised to a dominant unanimous decision victory. Although Alvarez won five rounds on all three judges' scorecards, in reality, he won no more than three rounds.

Canelo prefered to exercise an immediate rematch clause to face Bivol again, but had no choice but to face Golovkin (42-1-1, 37 KOs), as they previously agreed to fight before the bout with Bivol took place.

"I'm 100% focused on this fight [with Golovkin] because it's a dangerous fight," Canelo said. "But 100% looking for a second fight with Bivol."
