10 Rivalries That Will Define WWE In 2018
2. Seth Rollins Vs. Dean Ambrose
Former best friends - or, at the very least, teammates - fighting at WrestleMania has become a tradition over recent years. Last time out, it was Kevin Owens and Chris Jericho, and this one it's looking increasingly likely that Seth Rollins will take on Shield co-founder Dean Ambrose.
It's a feud that we've seen before, but things will be different this time round, with the Lunatic Fringe taking the mantle of heel for the first time since the original Hounds of Justice break-up, and Seth fighting on the side of good.
To many, it has the makings of a potential classic, and given that both men have seen their singles careers suffer this year after being forced back into the tag team game, it could also be exactly what they need to rediscover their respective mojos.
A deeply personal rivalry of this kind can't and won't be settled in a single bout either - so expect Seth and Dean to meet on at least three separate pay-per-views, with one or more of them contested under Extreme Rules. There will be blood.
