10 Rivalries That Will Define WWE In 2018

10. Charlotte Vs. Ronda Rousey

It seems now to be a matter of when, not if, Ronda Rousey makes her WWE bow and bumps into Charlotte, setting the wheels in motion for what many are calling a potential WrestleMania dream match.

We can't be certain that the UFC star is going to stick around for longer than a couple of months - for one thing, she has yet to officially retire from the Octagon - but, however short, this will be a defining feud for one big reason: money.

Vince McMahon is forever looking for a way to get his niche sports entertainment some precious mainstream press coverage, and signing up one of the most recognisable sports stars in the world seems like a pretty good way to go about doing that.

Charlotte will, in all likelihood, have to take a defeat on wrestling's grandest stage - but, as the jewel in the WWE women's division crown, there's no reason that a single loss should threaten her credibility too much, even if it comes against someone who has never before stepped into the squared circle.
