It's less than three weeks until Roman Reigns and Brock Lesnar face off at WrestleMania 34.

The pair are headlining WWE's biggest show of the year and will be fighting for the Universal Title. 

And it's not the first time that The Big Dog and The Beast are main eventing WrestleMania. 

They faced-off back in 2015 at the 31st edition - but of course, their big moment was interrupted by Seth Rollins, who cashed in his Money in the Bank to win the WWE World Heavyweight Championship. 

Nothing of the sorts will be happening on April 8 this time around, with the battle being billed as one of the most personal in recent years.

That's down to how Reigns has been acting in recent weeks. It's no secret that he's not the most loved WWE superstar, despite being pushed as the company's top man. 

In an attempt to push him as the face in the feud with Lesnar, Reigns has been cutting shoot-promos on Monday Night Raw, different to anything he's done before. 

He's recently been calling out Lesnar's attitude and status in WWE - suggesting that he's Vince McMahon's "boy" and suggesting that he "doesn't fear the bitch".

And those promos have helped him get over with the fans - and many of his promos have received a positive reaction.

With the feud turning very personal, Reigns is expecting a physical match in 20 days time but insists he's ready for anything Lesnar has. 

At the Royal Rumble back in January, The Beast showed just how brutal he can be by landing a stiff punch to Braun Strowman's face after his opponent had caught him with a knee.  

Even after that, Reigns is confident he can handle Lesnar and explained how he would respond if the former UFC star decides to shoot on him too. 

"If he throws two at me I'm throwing three back," Reigns told Cheap Heat, per Wrestling Inc.

"One of the easiest things about wrestling Brock Lesnar is that there isn't much thinking about it. It's just all physical stuff, and I've been doing physical stuff since I was seven years old." 

The Big Dog also suggested that his College Football background could serve him well at WrestleMania.

"I played Division-One Football at Georgia Tech, so I've seen and been around some of the best athletes in the world.

"What we do is a different form of entertainment and athleticism, but you still have to be an athlete in order to do what we do all year round, you have to keep yourself in that shape.

"I'm never scared to be able to push that button, let's go, if I have to protect myself, I'm more than capable, no doubt."
