Conor McGregor is set to return to the Octagon on Saturday when he fights Dustin Poirier.
McGregor's name always draws headlines and due to his relatively inactive UFC schedule over the years, his name inevitably becomes linked to WWE. Everyone from Drew McIntyre to Riddle to Becky Lynch has mentioned McGregor's name at some point in recent years.
Speaking to Digital Spy, Sheamus was asked about "The Notorious One" possibly entering the squared circle.
"He's teased [coming to WWE] a couple of times," Sheamus said. "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 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. But that's what it's all about, getting in there and seeing a different type of environment. In UFC you fight once a year or twice a year, in WWE we're fighting every week. We're taking big bumps every week, the physicality we go through is crazy. It's a different world we're in, I think it's definitely more competitive, it's definitely more physical. It takes more edge being in WWE than it does doing the UFC stuff. I'll probably get slated online for saying that but until you actually do our schedule you don't really realise how tough it is. But as I said, if he wants to come in and give it hand I have no bother stepping in the ring with him."
Sheamus was one of the many wrestlers to respond to McGregor in 2016 when Conor called the majority of WWE talents "pussies." You can find his comments from 2016 by clicking here.
