#4. Want: Finn Balor vs. The Undertaker

Fans have clamoured for several matches for the Undertaker that didn't come to fruition. Some wanted the Phenom to face Sting when Sting was briefly active in WWE while others have hoped for Balor and The Undertaker to face each other at the Show of Shows.
Well, you can count Balor as someone who also wants to take a crack at the Undertaker at Wrestlemania. Is this the year he gets his wish?
He teased the match himself with an Instagram post recently, possibly providing the fans with a match they'd want to see come April.
If the WWE wants to strike while the iron is hot, they should book this match for this year. Every year could be the last for the Undertaker and rather than seeing another match with John Cena in April, give the fans something they want.
Of course, the Undertaker wrestling in April isn't set in stone as of right now, but he usually rises from his crypt once the Royal Rumble has passed.
