Last night on Monday Night Raw, Paul Heyman made a ground-breaking announcement surrounding his client, Brock Lesnar.

Lesnar has been on hiatus from WWE since Survivor Series after he defeated Rey Mysterio, but he was expected back in early 2020 to build up for a title defence at the Royal Rumble.

Well he returned on Raw last night, but it turns out he isn't defending his WWE Championship after all.

Instead, Lesnar will be entering the Royal Rumble match, which is normally used by the winner to set up a main event match at WrestleMania.

As a world champion though, Lesnar is already guaranteed one right now, so it's a bit of a curveball to put him in the actual Rumble match - let-alone in the number one spot.

With WWE not being stupid enough to let him actually win the match (surely?), let's look at five men who could be booked to eliminate him and set up a match in Tampa at WrestleMania 36 against him.

CAIN VELASQUEZ

It has been rumoured for weeks now that Lesnar may be facing either Velasquez or Tyson Fury at WrestleMania 36, but with Fury tied-up with Deontay Wilder on February 22, that makes a Royal Rumble appearance impossible.

Velasquez however hasn't been seen on WWE television since his loss at Crown Jewel to Lesnar, and he no doubt wants his revenge.

So why not bring him back in the Rumble match and let Lesnar get his comeuppance for his brutal post-match beatdown?

It may not be the match the majority of the WWE Universe wants to see, but if backstage murmurs are to be believed, it looks like it may happen.

KEVIN OWENS

Owens is the most over babyface on Raw right now, and hasn't held a world title since the beginning of 2017, when he unceremoniously dropped it to Goldberg at Fast Lane.

But since Survivor Series, where Owens has been taking on Seth Rollins, KO has been getting great reactions and the fans would like to see him on top again.

He's almost certainly going to be in the Rumble match, and eliminating Lesnar would set up a first time ever match between the two men. 

SAMOA JOE

Joe's feud with Lesnar, despite only lasting a few weeks in 2017, was intense and memorable, but Joe deserved more than the six minutes he got against Brock at Great Balls of Fire.

The Samoan Submission Machine is back as a babyface now, and like KO deserves a run as Raw's top guy.

You'd be a fool to not want to see Lesnar and Joe brawl with each other for 15 or more minutes - it would be an absolute slobberknocker!

DREW MCINTYRE

McIntyre has told the fans that 2020 will be his year, and in recent weeks he's began developing a humorous side to his Scottish Psychopath character.

As a 'tweener' character who is neither a good or a bad guy, how good would it be to see him throw Lesnar over the top rope and secure himself a WWE Championship match?

McIntyre could then fulfil his prophecy from over 10 years ago as the 'Chosen One', and defeat Brock at WrestleMania - which is what fans would rather like to see.

KOFI KINGSTON

Despite Kofi being a SmackDown superstar, there's nothing to stop Raw making a trade for the New Day (if they're not Tag Team Champions still), and Kingston taking Lesnar out of the Rumble would be perfect revenge for his title loss in October.

Most fans believe it was unjust in the way that Lesnar won the WWE Title, and even if he took on Lesnar at Mania and lost, giving him a lengthy match with the Beast Incarnate would majorly make up for how WWE did Kofi dirty.

MATT RIDDLE

Obviously having an NXT superstar eliminate Lesnar is very unlikely to happen, but for years Riddle has spoken about wanting to retire Lesnar.

So why not capitalise on that and have the King of Bros take him out for the first time?

Riddle would no doubt work perfectly on the main roster and has mainstream appeal, and seeing two former UFC fighters go at it will appeal to a lot more than just wrestling fans.
