WrestleMania is WWE’s biggest pay-per-view, but it wouldn’t be what it is without SummerSlam. The second biggest PPV of the year is often used to set up big matches at the following WrestleMania, and SummerSlam 2015 at Barclays Center in Brooklyn should be no different.

Two years ago, Daniel Bryan’s battle with The Authority began when he won the WWE Championship at SummerSlam, and the storyline culminated with him regaining the title at WrestleMania 30. Brock Lesnar shocked many WWE fans by pummeling John Cena and winning the WWE World Heavyweight Championship at SummerSlam 2014, only to lose the belt at WrestleMania 31. In just a few short weeks, Lesnar will face The Undertaker, and Seth Rollins will defend his WWE World Heavyweight Championship in two matches that should have major implications for WrestleMania 32.

With SummerSlam and an NXT special set to take place in the same building on back-to-back nights, there will be major developments in WWE on the weekend of Aug. 23. Below are five predictions for SummerSlam 2015.

The Undertaker Will Visit Supplex City

Lesnar might not win his match against The Undertaker, and the Deadman is now the betting favorite to be victorious in the SummerSlam main event. But for the majority of the match, Lesnar should continue to dominate, much like he’s done for the past year.

Even when Lesnar broke The Streak at WrestleMania 30, The Undertaker controlled the early part of the match. Lesnar has failed to get the pinfall in three of his five matches since then, but he’s been dominant in each one, supplexing his opponents from bell to bell. After signing Lesnar to a multi-year contract, WWE has a lot invested in Paul Heyman’s lone client on the roster. The match might end with The Undertaker hitting a Tombstone Piledriver for the victory, but it could be pre-empted by double-digit supplexes and a few F5’s.

John Cena vs. Seth Rollins Will Steal The Show

It’s looking likely that Cena will put his United States Championship against Rollins’ WWE World Heavyweight Championship at SummerSlam. While Cena has never been known as the best in-ring performer, he’s raised his game to such a level in 2015 that his match with Rollins has become a must-see event.

Cena has undeniably been WWE’s best performer this year, having matches with Lesnar and Kevin Owens that have been among the year’s best. His match with Rollins on the July 27 edition of “Monday Night Raw,” was terrific, and there’s little reason to believe the two wrestlers won’t be able to duplicate that on Aug. 23. With two titles on the line and a finish that won’t be easy to predict, Cena and Rollins could tear the roof off of Barclays Center.

There Will Be Two Divas Matches

WWE appears to be serious about giving the Divas more time to wrestle. Since the recent NXT call-ups have joined the main roster, the Divas have been consistently getting two matches on “Raw.” It only makes sense that there will be two Divas matches on what is now a four-hour show.

It won’t be difficult to make two matches, considering nine divas have been featured prominently on WWE TV over the last few weeks. Charlotte might be the most likely candidate to challenge Nikki Bella for the Divas Championship, and at least one of the matches could be a triple threat. SummerSlam 2014 featured two Divas matches, as Paige beat AJ for the title, and Stephanie McMahon defeated Brie Bella.

Kevin Owens Will Go 1-1 on SummerSlam Weekend

Owens will likely have matches on both Saturday and Sunday. He’s scheduled to face Finn Balor for the NXT Championship in the main event of NXT TakeOver: Brooklyn on Aug. 22 at Barclays Center, and it’s looking like he’ll face Cesaro in a match at SummerSlam.

It would make little sense for Owens to defeat Balor, considering he’s been on the main roster since May and his time in NXT is nearly over. But a loss on Saturday should mean a win on Sunday for Owens, as WWE looks for him to remain as one of the company’s top heels. Some fans have complained that WWE has “buried” Owens with two straight losses to Cena, but a win over Cesaro at the PPV would put him in a good position going forward.

Sheamus Will Cash-In

SummerSlam has become the site of a few Money in the Bank cash-in attempts in recent years. Alberto Del Rio stole the WWE Championship from CM Punk in 2011, and Randy Orton took the belt from Bryan with the help of Triple H two years ago.

Sheamus might not win the WWE World Heavyweight Championship, but the potential title vs. title stipulation could make a cash-in attempt more likely. Inserting Sheamus into the feud between Rollins and Cena could allow Rollins to win future matches without Cena being pinned. Sheamus might not be over enough for him to hold the belt for a prolonged period of time, but Brooklyn might be the perfect place to make him the company’s top champ, since he would draw a lot of heat from the New York crowd.
