#1 Roman Reigns vs. Seth Rollins vs. Cesaro
After Roman Reigns defeated Cesaro at WrestleMania Backlash, Seth Rollins made his way out to the ring and stood face-to-face with his former Shield brother. However, he then proceeded to attack an already injured Cesaro and laid him out with a vicious beatdown.
Seth Rollins and The Swiss Cyborg have been feuding against each other for the last few months and even faced each other at WrestleMania 37, where the latter emerged victorious. After the events of WrestleMania Backlash, the two will likely clash once again.
However, WWE could make things more interesting by adding both of them to the Universal Championship picture and letting them face Roman Reigns in a triple threat match at WWE Hell in a Cell 2021.
There have been a few teases recently of issues between Seth Rollins and Roman Reigns. WWE has enough time to build a storyline where Rollins gets on the nerves of The Tribal Chief, leading to a triple threat feud and match at next month's pay-per-view.
