#3: Batista v Roman Reigns.

Batista has been pretty vocal about a return to the squared circle in the past few months. Batista was one of the biggest Superstars in WWE during the Ruthless Aggression Era along with John Cena and Edge.
His return to WWE in 2014 did not go down well with the fans. WWE should make sure they make the correct decisions this time around. Placing him in a feud with Roman Reigns will make for an electric atmosphere.

Both these individuals are known to have hard-hitting matches, and together they could create magic in the ring. They have faced off before on an episode of RAW in 2014, but a match at the Grandest Stage of Them All will be a delight to watch.
Imagine Roman Reigns winning the Universal Championship at WM, coming out on RAW next night, only to be interrupted by the returning Animal! The WWE Universe will go wild!
