WWE's Sheamus: McGregor joining company is a 'matter of when,' not if

WWE Superstar Sheamus is confident Conor McGregor's long-teased move to professional wrestling will eventually become a reality.

"He's teased (coming to WWE) a couple of times," Sheamus said during an interview with Stephanie Chase of Digital Spy. "He's still staying active, he's a lad who's won belts, he's done a lot, so I think he's that type of person who's always trying to try his hand at something different.

"I think WWE would suit him down to the ground. You know, we've had a lot of people come in and out, (Floyd) Mayweather came in, a lot of celebrities have come in, a lot of sports people. So I don't think anyone would raise eyebrows if he came in to WWE. I don't think it's if, I think it's a matter of when to be honest."

If that does happen, Sheamus would be willing to square off against McGregor.

"If he wants to come in there with me, that's grand. He might get the fight of his life there, he might get couple of slaps he's not used to," Sheamus said. "But that's what it's all about, getting in there and seeing a different type of environment."

McGregor returned to the Octagon for the first time in a year on Saturday at UFC 257, losing to Dustin Poirier via second-round TKO.
