WWE Superstar Roman Reigns has lifted the lid on what it's truly like to share the ring with Brock Lesnar, describing his working relationship with the latter as very challenging due to the nature of how rough and physical he is in between the ropes.

The Undisputed WWE Universal Champion Reigns was recently on Logan Paul’s Impaulsive podcast, despite the fact they are going one-on-one at Crown Jewel in November, and on it he acknowledged that Lesnar has been his biggest rival in the company, stressing the competitive and enormous nature between the duo.

"Me and Brock have been at a bunch of huge shows together," Reigns said, as per WrestlingINC, as he cited "big pay-per-views" including WrestleMania as their high-profile platforms.

"I would definitely say he's been, thus far, my biggest rival."

Roman Reigns recently defended his Universal Championship title against Drew McIntyre as he defeated the Brit at the just concluded WWE Clash at the Castle pay-per-view staged at the Principality Stadium in Cardiff, Wales.

Speaking further on The Beast Incarnate, though, Roman Reigns admitted Lesnar’s aggressiveness in the ring was tough to deal with and expressed his displeasure toward the 45-year-old’s belligerent approach to fight.

"F****** Brock Lesnar, man, he picks you up and throws you on your head — there's nothing nice about that," he said.

"It's very tough to work with a human being like that — that some call him, like, the alpha male of our species. And it's true, he really is what he is.

"I mean, he's a great businessman, but at the same time he has a legitimate background of MMA that when you get in the ring, there has to be some kind of protection of that legitimacy.

"We can't just put him in there with anybody, but at the same time, when you get in there with him, you kind of understand it's gonna be a bit of a ride, but there's gonna be a lot of eyeballs on it. So that always makes it better,” he added.
