#3 The Rock Vs. Roman Reigns
In October last year, Roman Reigns' entire future as a superstar was put in jeopardy, when the former Universal Champion announced his leukaemia relapse.
Fortunately, Reigns has recovered and is no doubt hungry to return to the top of the mountain, which was a spot once held by his relation The Rock.

A match between these two goliaths would definitely be WrestleMania worthy, as The Rock's return in 2011 showed that the Hollywood megastar could still go in the ring.
It would also hopefully please those fans who feel that Reigns (through no fault of his own) has been too much of a feature in the Universal title picture, and having a non-title feud against his own flesh and blood would help elevate the Big Dog even more, whilst someone else held the gold.
