#3 To prove he's still the top star
Seth Rollins is the WWE Universal Champion, but is he the biggest star in WWE today?
In theory, he should be. After all, he is the top champion on Monday Night RAW, the top show in the entire Sports Entertainment juggernaut. And yet, there is an argument that SmackDown Live Superstar Kevin Owens is bigger than Rollins right now, as his continuing feud with the Best in the World Shane McMahon has fans hooked.

Even worse, many could even say that The Fiend, Bray Wyatt, is a bigger star than Rollins at the moment, despite the former WWE Champion having just one match in months, when he defeated Finn Balor at SummerSlam.
With a new King of the Ring soon to be crowned, the WWE really needs to show that whilst these other stars are great, there is only room at the top for one top Superstar.
That Superstar should in theory be the Universal Champion, and having Rollins compete twice at Clash of Champions will help remind the fans just how good he really is.
