#4 Shane McMahon
There appears to be unknown animosity between Shane McMahon and Triple H. With Triple H already making his return just a few days ago, an encounter with Shane McMahon would be an interesting one and would cause a lot of buzz.
The WWE Universe have speculated and anticipated a match between the two for quite some time now. The issues between these two corporate giants would best be solved in a WWE ring at Wrestlemania.
Triple H would most likely challenge Shane's authority as the Commissioner of SmackDown live. The power struggle between the two is likely to blow up and lead to a showdown at Wrestlemania.
Expect Stephanie McMahon to take her husband's side whereas Shane might just get the Chairman's backing. A match of such magnitude would have big stipulations and the implications would be severe. Sledgehammers and high-risk manoeuvres would dominate this match.
