#1 Undertaker
The John Cena vs Undertaker clash at Wrestlemania is one that has been rumoured for a long time. Even though many of us believed his match against Roman At WrestleMania 33 was his swan song, reports erupted that the taker may be having one last match with John Cena at the upcoming WrestleMania.
It was expected that the announcement would be made on the RAW 25th-anniversary episode, but that did not happen. It was then expected that 'Taker will interfere in the Chamber match to cost Cena the victory, but that also did not happen; which has left fans wondering whether or not the match will take place at all.
It is still quite possible that John Cena issues a challenge to the Deadman at the upcoming episode of RAW and we will just have to wait and see if this iconic match will be a part of this year's WrestleMania or not.
