5 WWE Superstars that could potentially dethrone Brock Lesnar as Universal Champion 

#4 Matt Riddle

Matt Riddle

There are few in WWE who can boast the legit MMA background of Brock Lesnar, but one that most certainly can is the Original Bro, current NXT superstar, Matt Riddle. This has been a goal for Riddle since coming into the wrestling business, and given how well he's transitioning to WWE, he'll be on the main roster very soon.

He hasn't stopped vocalising it since joining WWE either, and he's put it out there that much at this point, that it almost has to happen. Given that Brock just won the title, it's unlikely that he'll drop it in the next few months, and if NXT can continue building Riddle the way they have, this is a very real possibility.

Riddle isn't known by the whole world yet, but if WWE bring him up and push him straight away, he'll be a megastar, as he has everything that the company wants in a top star.
