WWE No Mercy takes place later today at the Staples Center in Los Angeles, California, and the Monday Night RAW exclusive pay-per-view has some very interesting matches that fans should be excited about.

One of those matches is the WrestleMania-worthy match between John Cena and Roman Reigns. This match isn't even expected to go on last on the show, which is surprising of a match of this caliber and the superstars involved.

The main focal point of their feud so far has been their promos, which have become rememberable for the comments made by each superstar, such as Cena saying to Reigns: "I can do this better part-time better than you can ever do this full-time," in relation to being the top guy in the WWE.

Most WWE fans would agree that overall, The Leader of the Cenation has come out on top in this side of their feud. However, The Big Dog also left some parting words earlier this week on RAW which could swing it the other way in some people's eyes.

A win for Reigns at No Mercy would make him the permanent face of the WWE, but the one thing Cena wants to see more from his opponent tonight is connecting with the audience, and he doesn't think the company's creative writers have been able to do that. He believes this is the one thing Reigns truly lacks that stops him from being the unquestionable face of the company.

Cena said during an appearance on the on E&C’s Pod of Awesomeness, according to IWNerd: “My biggest hang-up with Roman Reigns as the front-runner of the WWE is the fact that he seems to lack in his ability to communicate with the audience. And that is not that he can’t because I know Roman. Socially, he is a great guy. He has a presence that is undeniable so I know it’s there.

"Nobody has had the nuts to try and bring it out of him, nobody. My job in the WWE is to either be the best or to be a vehicle for the best. So I was going to go out there and rip that kid every single week, until he said enough. I thought his promo on Monday was brilliant”

Cena said he loved the promo because it was passionate and it came from Reigns himself. He also believes the reason why we don't see more of this is that nobody else challenges him on the microphone every week.

“I think Roman knows who he is, he just doesn’t have everybody every week to tee off on him. We kind of matriculated with some really good talkers, so you either sank or swam every single f’n week. There was somebody to knock you down a peg, no matter what every week. It is rare that, that exists now a days.”

Cena is expected to take some time off after No Mercy this weekend for other projects, so how Reigns reacts in the ring after the event will be interesting to see.

Hopefully, he listens to Cena's advice and brings more passion to his promos, as that could be the missing piece that helps him connect with the WWE audience and truly become the face of the company.
