3. Roman Reigns vs Triple H
WWE.comThis is the most likely on the list, as the seeds for this were plante back with Evolution's feud with The Shield: as the two big dogs of their respective groups, there was a palpable tension whenever the two squared off. The WWE have kept that alive since, right up to recent confrontations in which a suited Triple H has backed off from a stare-down with the ever rising Reigns - you get the feeling that one of these days, Triple H won't be wearing a suit and he won't back down. As the company's next huge star, you know that Triple H will want to personally put Reigns over on as big a stage as possible, which means this feud is happening on one of two PPVs: Summerslam or Wrestlemania. The match will make Reigns in the eyes of the company and the fans and if it happens as soon as Summerslam, expect Reigns to win the Royal Rumble in January and grab that Wreslemania headline spot.
