#1 Seth Rollins winning the Universal Championship

Brock Lesnar has been the undisputed WWE Universal Champion for most of 2017 and 2018. With Roman Reigns' absence from WWE due to leukaemia, there hasn't been any program of worth involving the championship. While Braun Strowman is set to face the Beast Incarnate at the Royal Rumble PPV, Seth Rollins is earmarked by WWE management as the face of WWE.
Seth Rollins has had a stellar 2018 with Intercontinental and Raw Tag Team Championship Reigns to his name. With his latest segment involving Triple H indicating that Rollins is not going to be in the Intercontinental Championship scene any more, he showed off a more vicious side of himself and surely more that is needed on screen if he were to beat either Brock Lesnar or Braun Strowman for the coveted Universal Championship.

With the lack of Lesnar's presence hindering RAW's rating and proceedings, Seth Rollins could be the ultimate solution to all of these problems and is something that is quite inevitable.
