Kamaru Usman has called out Saul 'Canelo' Alvarez again as he considers switching from MMA to boxing.

The reigning UFC welterweight champion has called out Canelo Alvarez once more as he suggested it is only a matter of time until he swaps the Octagon for the squared circle.

Nicknamed 'The Nigerian Nightmare', Usman will defend his welterweight title in a rematch against the unfancied Leon Edwards later this year.

But it seems he is already looking past his next opponent as he eyes a date with the Mexican in September.

Usman told TMZ: “In 2022, I’m gonna shock the world.

“July, International Fight Week, I’m gonna fight Leon Edwards.

"God willing I get through Leon Edwards, September, Mexican Independence Day, I will stop Canelo Alvarez.

“Absolutely I see myself winning that fight and that’s the thing that a lot of people fail to realize.

"A lot of people, because they think they can’t do something, they try to put that upon you. ‘Oh, you can’t do that. It can’t be done.’ Everything can’t be done until it’s done.

"So a lot of people are gonna say, ‘You can’t do it. No, he’s too good, he’s too skilled, too strong.’

"Yeah, they said that about Tyron Woodley. He’s too big, he’s got knockout power, he’s fast, he’s explosive.

"What happened? I told him I was gonna dominate him for five rounds and I did that. I’m not gonna [sic] step in there if I don’t think I can get it done.”

Canelo, 31, is widely regarded as the best pound-for-pound boxer on the planet after his brutal knockout win over Caleb Plant last November took his record to 57-1-2 (39 KOs).

But the 35-year-old American is confident he can end the Mexican's eight-fight undefeated streak despite his obvious lack of experience.

He added: “Boxing is dead at the end of the day and I’m not saying there’s not good boxers, there’s some fantastic boxers.

“Errol Spence Jr, I mean there’s a ton of guys that I could go down and really tell you that are fantastic fighters.

"But boxing is dying. At the end of the day, everybody wants to be entertained. And when have you ever seen the pound-for-pound against the pound-for-pound?

“He’s walking around saying payday, payday... absolutely. It’s the biggest payday you are ever gonna [sic] make. I understand that he gets paid, he makes money.

"But fighting me is the biggest payday he’s ever gonna make. We talking nine figures, for sure.”
