There won't be no moving, there won't be no running - according to Floyd Mayweather Jr. (49-0, 26 KOs).

The former five division world champion claims that he's planning to fight "toe to toe" with UFC superstar Conor McGregor on August 26th at the T-Mobile Arena in Las Vegas.

Mayweather, now 40 years old, is breaking a two-year retirement. He walked away from boxing in September of 2015, after dominating Andre Berto over twelve rounds at Las Vegas' MGM Grand.

Mayweather is not counting out his next opponent, despite McGregor’s lack of traditional boxing competition. McGregor is a two-division champion in the Ultimate Fighting Championship, but has never boxed professionally.

Many observers expect Mayweather to use his boxing ability, and his footwork, to dominate McGregor with ease.

But Mayweather insists that he's no longer the same fighter. He claims that his body is giving him hell in training camp and he can't get his footwork going like he did in the past.

Because his footwork is not on par like it was before, Mayweather expects a showdown filled with fireworks. 

“He wants to win bad,” Mayweather said. “He really wants to win bad, extremely bad. With other fighters, it plays out two ways when you’re facing Floyd Mayweather. You’ve got some guys that play it safe. You’ve got some guys like Maidana that go straight for the kill. He’s going to come out and go for the kill like Mayweather-Maidana I. He’s going to come out and go for the kill. He’s a heavy hitter, so I’ve got to be cautious. Remember, I’m older, so I can’t move like I used to move, so it’s basically going to be a toe-to-toe battle.”

“It’s going to be exciting. He’s going to come fight. He’s going to come out. He’s upset. I’ve seen it before. When these fighters get upset with me, they come out like they’re going to try and kill me. My job is to do what I do, just keep my composure. He does have a chance. Every time two warriors go out there and compete, anything can happen. We just saw a week ago, two weeks ago, a guy who started boxing at 18, a teacher, beat one of the best fighters of all time, which was Manny Pacquiao, so anything can happen in a combat sport.”
