The Rock

Another match that has been rumoured for years. Mutterings of this bout taking place began at Wrestlemania 31 when The Rock and Ronda Rousey had an in-ring confrontation with Stephanie McMahon- leading many to think that it could lead to a mixed tag team match between the four at some point in the near future.
Those rumours never come to fruition, however, and talk of the two meeting in the ring one last time has died down ever since. This one does definitely seem to be the most unlikely to take place on this list, but it certainly seems likely that if The Great One decided to step back between the ropes, then Triple H would be first in the queue for a match with him, and what better place to have that than at Wrestlemania.
