Gennady Golovkin will get knocked out in his trilogy fight with Saul 'Canelo' Alvarez , former super-lightweight world champion Amir Khan has predicted.

The WBA middleweight champion will renew his rivalry with the Mexican on September 17 at the T-Mobile Arena in Las Vegas.

Canelo controversially ended Golovkin's reign as WBA and WBC king in their rematch in September 2018 via majority decision, and British boxing legend Khan expects his former opponent to get the job even done more emphatically third time round.

When asked for his prediction for the trilogy fight, Khan admitted that he fears Canelo's power and speed will be too much for Golovkin.

Amir Khan makes prediction for Canelo Alvarez vs Gennady Golovkin 3

"Everybody has their own opinion. So it’s a third fight. You got to remember that Canelo is at the peak of his career.

“You get me? He’s old. He’s strong.

"He’s settled now. His weight is amazing. He holds the weight well.

"Power, speed. I think in that fight, I could see Canelo [stopping Golovkin]. No disrespect to Triple G - what a beast he is - but you’ve got to remember he’s getting older, and he’s been in the game for a long time.

"He was in the same Olympics as me in ’04. I just feel like Canelo is the fresher guy that hasn’t been in that many wars.”

He told FightHype: “It’s one of my best punches, to the body, right?

"I’m gonna work whatever, head, body, but my goal is to end this fight before the 12th round. So, whatever I need I’m gonna do it in the ring.

“This kind of fight, our styles make this fight perfect. That’s why it’s a trilogy. We had two great fights because our styles make the fight perfect.

"And I think this fight is gonna be a good fight too. But I think I’m more mature, I’m in my prime, I feel confident. I think that’s gonna be the difference.”
