3. Seth Rollins vs John Cena
Cena and Rollins have been at one another's throats for a while now, but there's still room for one more chapter. Technically, Rollins should have a rematch for the US Championship he lost on Sunday - although it might not be surprising if he passes up on this opportunity to focus on defending his WWE Championship. Cena, however, should be as keen to step into the ring with Rollins as ever, even if it means putting his newly-won title on the line. Should this feud restart, it certainly shouldn't last very long, but could be a nice opportunity to further galvanise Seth's in-ring credentials. The champ has suffered from a strange duality throughout his reign, scraping through matches despite being portrayed as an absolute ass-kicker for the majority of them. Perhaps one last match against Cena can turn this around.
