#1 Controversial finish at Greatest Royal Rumble

If nothing else, Roman Reigns deserves a rematch due to the controversial nature of the finish at Greatest Royal Rumble While Lesnar was ultimately ruled the winner after he got speared through the cage wall by Reigns, it was seen by countless fans that Reigns's feet were actually the ones that touched the floor first.
Of course, a lot of that has to do with how Reigns practically DDT'd himself in the process of the finishing blow, but its hard to deny Reigns a rematch if he actually did get screwed by a wrong decision made by WWE officials. In fact, this alone is grounds for a rematch between the two later on down the line.

In the end, WWE needs to finish what they started and the controversial finish at Greatest Royal Rumble at least hints at the possibility that WWE will do that. If they don't however, it is going to be a very confusing transition for WWE storyline wise and would render everything the company did in the build-up to WrestleMania 34 completely meaningless
