#5 Roman Reigns
Many fans do choose to forget that between his tired return to the top at this year's Wrestlemania season, Roman Reigns was revitalizing his career with a somewhat muted but still great Intercontinental title run. In fact, it was Reigns who first revived Cena's much vaunted Open challenge with stellar bouts against the likes of The Miz and Samoa Joe.
He had a wild mesh of styles to compete with and proved that if it weren't for WWE's terrible booking of him and Vince McMahon's manic wrestling style preferences Roman could definitely be a worthy big dog. Reigns'character has pretty much been hurt by management despite being in his favour, but a match against Rollins might remind some, how stellar he is in the ring despite his past few matches.

More often than not extensively profound matches between the two former brothers have not occurred apart from Money in the Bank in 2016 and to see Rollins and Reigns tear the house down once more would be fun. Plus it might even be helpful if this led to Roman's much-needed heel turn.
