A Floyd Mayweather-Conor McGregor fight continues to seem more inevitable. The drumbeat for the megafight got louder Monday, when legendary boxing trainer Freddie Roach said he heard the fight would happen from none other than Mayweather himself.

Speaking on “The MMA Hour,” Roach told host Ariel Helwani that about three months ago, Mayweather stopped by his gym “a couple of times.” He said that Mayweather asked if McGregor had talked to the 56-year-old trainer, who has worked with several MMA fighters, in addition to the likes of Manny Pacquiao, Miguel Cotto and Julio César Chávez Jr.

Roach said he told Mayweather that he had not heard from McGregor, to which the retired boxer replied, “If he reaches out and wants you to train him, I would take that job because I am going to fight him and we can all make a lot of money.”

“So, according to Mayweather, yes, he told me he would fight [McGregor], and everything is pointing in that direction right now,” Roach told Helwani.

Roach added that “at one point, [he] didn’t think it was possible” for such a cross-sport matchup to take place, because he had tried to arrange something similar with one of the Klitschko brothers when he was training former UFC champion Andrei Arlovski a few years ago. However, “We’re in a different era now,” Roach said.

“It looks like it’s gonna happen,” he added. “Everything is pointing in the right direction.

“I think Conor will have his hands full with a boxer like Floyd. But he’s sellable, he’s making some noise.”

As for McGregor’s chances of defeating Mayweather, which many observers think are very slim in a boxing-only match, Roach noted, “He is a pretty good striker.”

“The thing is, Floyd is a great boxer,” he continued. “He’s really good at hitting and not getting hit, and so forth. I think it would take a long time for Conor to get ready for a boxing match, a pure boxing match. But, you know, one punch can change everything. It’s the sport we’re in. So I’m not going to count him out completely.

“I think Mayweather is the favorite, yes, but I would never count anyone out. Because [McGregor] throws, he throws hard and he’s not afraid to throw.”

Roach also claimed that Mayweather had told him that he would stay retired, except for a possible bout with McGregor. That jibes with comments Mayweather made in January, when he told ESPN, “Only thing that I’m probably interested in is the Conor McGregor fight. I’m a businessman and it makes the most business sense, I think.”

Earlier this month, an Irish newspaper reported that the two superstar fighters had agreed to terms on a match, but Mayweather quickly issued a statement claiming that there had been “no deals made.” That’s not the same as saying that no deals were imminent, and at this point, it seems more likely than not that one will arrive, even if it involves some cajoling to get the UFC, McGregor’s employer, on board.

Roach said that it would be an “honor” for him to be able to train the Irishman for a Mayweather fight, and, from the sound of it, he may well get his chance. Roach cautioned the ever-confident McGregor, though, saying Monday, “When that bell rings, he better be ready, because he is fighting one of the best boxers of his era.”
