WrestleMania 33 only ended a few days ago, but it’s never too early to look ahead towards WWE’s next marquee event. WrestleMania 34 is scheduled for April 8, 2018 in New Orleans, and some wheels have already been set in motion for the pay-per-view’s main event.

While it’s just about impossible to make predictions for the entire WrestleMania 34 card, a few things appear to be all but certain. Roman Reigns, Brock Lesnar, and Triple H will be near the top of the card. John Cena will have a marquee match, and there’s a good chance Kurt Angle will return as an in-ring performer. The Undertaker won’t have a match after retiring at WrestleMania 33, though he could headline the 2018 WWE Hall of Fame class.

Here are some predictions for the biggest matches on the WrestleMania 34 card:

Brock Lesnar vs. Roman Reigns

Whether it takes place at SummerSlam or WrestleMania, this match is going to happen at some point in the next 12 months. WWE already planted the seeds for the match when Paul Heyman called out Reigns on the episode of “Monday Night Raw” after WrestleMania 33. Lesnar and Reigns are the only two superstars to defeat The Undertaker at WrestleMania, and it only makes sense for them to face off on the Grandest Stage of Them All. Reigns has headlined WrestleMania in each of the last three years, and WWE will likely keep him in that spot for the foreseeable future.

Triple H vs. Kurt Angle

Triple H always find himself in one of the biggest matches at WrestleMania, and Angle is likely to find his way back inside of a WWE ring at some point. With Angle being named the new general manager of “Monday Night Raw” and Triple H technically being his boss, it’s easy to see the two legends clashing and building towards a match in New Orleans. If Angle doesn’t face Triple H, look for him to have a match against one of the top heels on “Monday Night Raw.”

AJ Styles vs. Shinsuke Nakamura

It’s the match that many fans wanted to see at WrestleMania 33. Now that Nakamura is on WWE’s main roster, there’s a real chance that it could happen. The two wrestlers put on a show at New Japan Pro-Wrestling’s Wrestle Kingdom 10 in January 2016, and they’d probably have the best match on the WrestleMania 34 card. Styles could become WWE’s most popular babyface by the end of 2017, and Nakamura should have no trouble getting over after leaving NXT.

John Cena vs. Samoa Joe

It’s pretty evident that Cena’s days as a true full-time performer are done, but he’ll still have matches at WWE’s biggest PPVs. That means he’ll probably face one of the top heels in WWE at WrestleMania 34. When looking at the roster, few superstars make more sense as Cena’s WrestleMania 34 opponent than Joe. Cena has already had major programs with Bray Wyatt, Kevin Owens, Rusev and The Miz in recent years. A guy like Baron Corbin could be in a position to face Cena within the next year, though Joe is more of a certainty to be a top guy in WWE by 2018.

Charlotte vs. Asuka

There’s a good chance the women’s title matches will feature at least three wrestlers, considering that’s been the case in each of the last two WrestleManias. But if any two female superstars are going to have a singles match, it’s likely to be Charlotte and Asuka. Charlotte is the most dominant woman on WWE’s main roster, and Asuka still hasn’t been pinned or submitted during her year and a half in NXT. The NXT champ could be on the main roster shortly after SummerSlam, giving her enough time to earn a title shot at WrestleMania 34.

Finn Balor vs. Bray Wyatt

It looked like Balor would be on the WrestleMania card in each of the last two years, but circumstances prevented him from competing at WWE’s biggest PPV. As long as he’s healthy, he'll have a match at WrestleMania 34. WWE showed what high hopes they have for Balor by making him the first-ever WWE Universal Champion, and he’ll be one of the company’s top babyfaces in no time. His “demon king” alter ego would make for a perfect foil against Bray’s unique character, and Balor’s association with The Club makes a feud with The Wyatt Family even more plausible.

Seth Rollins vs. Bobby Roode

Retaining the NXT Championship on the night before WrestleMania 33, it’s unknown exactly when Roode will make his way onto the main roster. But there’s no question that he has a chance to be a star in WWE, and considering he’ll be 40 years old in May, WWE probably won’t waste much more time before calling him up. Roode could face any number of babyfaces at WrestleMania 34, but Rollins should be among the leading candidates. He’ll be a top-two babyface in WWE by 2018 if he’s booked correctly, and a feud with Roode could be one of the most interesting storylines heading into WrestleMania 34.
