5. Roman Reigns Vs. Brock Lesnar (c) Vs. Seth Rollins - WrestleMania XXXI
Looking back, this was the only decision WWE could make in order to save the main event of their biggest show of the year. This match started out as a one-on-one between champion Brock Lesnar and Royal Rumble winner Roman Reigns, before Seth Rollins came out mid-match to cash in his Money in the Bank contract. If you weren't aware of that then I'm surprised you are even reading this. This was all about the moment and spectacle, less about the match. Before the appearance of Rollins we had seen Lesnar brutalise Reigns with a barrage of suplexes, before Reigns began an improbable comeback and seemed as though he was able to pull it off. The crowd wasn't entirely sure what to do, not ready to accept Reigns as their lord and saviour despite the desperation of the WWE for it to happen. Enter Rollins. Even if the finish was a foregone conclusion from that point on it was still a marvel to see, and chills made their presence felt up the spines of everyone watching the event. Rollins delivered a Curb Stomp to Reigns and that was that, a moment that will live long in the memory for all who saw it.
