WWE WrestleMania 2015: Stars Under the Most Pressure at PPV

As is perhaps expected with the biggest show of the year, WWE WrestleMania 31 will heap pressure on the company's Superstars like never before.

Everyone will be under pressure to help ensure WrestleMania goes off with a bang, but there are some stars on the roster who will be feeling the heat more than others.

For example, you don't have to be a genius to work out that, given how he has yet to compete in a WWE ring, Sting's performance will likely attract more attention than anyone else's.

He and Triple H have had precious little in the way of interaction as we head toward WrestleMania, which will only ramp up the pressure on the duo when the event rolls around. Sting will be under pressure to show he can still deliver in the ring and is indeed capable of pulling off such a high-intensity and much-talked-about match as this one.

Another Superstar who will be under pressure is certainly Bray Wyatt. It's been a lean few months for Wyatt, who has had a couple of subdued rivalries, at least by the standards he set himself throughout the early part of 2014.

In truth, Wyatt has struggled to sustain a healthy run of momentum ever since his defeat to John Cena at WrestleMania last year. That's why this year's show seems more important for him than most, especially considering the magnitude of his opponent.

A match against The Undertaker is huge enough, but when it takes place at WrestleMania, it suddenly becomes a defining match for Wyatt's fledgling career.

Wyatt has been trusted to put all the buildup into the match due to The Undertaker's absence, and if he can get through the other side of this contest with some momentum behind him, he might well be looking up.

In fact, he might be looking at the top of WWE—specifically the WWE World Heavyweight Championship.

And after WrestleMania, the titleholder could well be Roman Reigns, another Superstar who will be under pressure.

Reigns is struggling to get himself properly over with WWE fans since that controversial Royal Rumble win, and you can imagine that WrestleMania will be an important night for his character development in the long term.

It will be worth it to keep an eye on whether WWE decides to keep Reigns as a "tweener" into and beyond WrestleMania, but regardless, Reigns simply has to deliver against Brock Lesnar.

He's under pressure in the buildup to the event too, especially as most of his promo work is going to be done against the superb Paul Heyman.

But when WrestleMania does arrive, it will be vital for Reigns to put on a strong show.

There are plenty of doubters out there when it comes to Reigns' ability to put on a high-quality match inside the ring, so doing that on the biggest pay-per-view of the year will go some way toward silencing those critics.
