#1 The Undertaker vs Daniel Bryan - WrestleMania 34
Orginal match: The Undertaker vs John Cena
When it was announced on WWE.com that Daniel Bryan was cleared to make an in-ring return, the entire professional wrestling world erupted and began to speculate who the Leader of the Yes Movement would take on in his first match back. While his return match saw him team up with Shane McMahon to face Kevin Owens and Sami Zayn, many wanted to see the former WWE Champion be in a singles match upon his first match back in three years.

On the same night, The Undertaker returned and looked like he was in the best shape he had been in for years. Even The Deadman himself said he was planning on having a 25-30 minute match, but he ended up competing for just three minutes at WrestleMania 34 against John Cena.
Daniel Bryan could have been the man to face The Undertaker at WrestleMania 34, and he could have challenged a man he has never faced before in WWE - The Undertaker.
Following the WrestleMania clash, it could have served as a motivator for Daniel Bryan to turn heel and start his WWE Championship reign approximately five months earlier than originally slated.
