Dean Ambrose
The only member of the Shield without a championship, Dean Ambrose has still been a dominant force since returning in the Summer.
With Roman occupied with Braun Strowman, Ambrose has been teaming with Rollins to take on the Dogs of War, who currently hold the RAW Tag Team Championships.
However, mind games have already begun, with the Dogs attempting to coerce Ambrose away from his Shield brethren.
Whilst Ambrose has resisted their temptations, the wounds of Rollins' betrayal in 2014 will still be fresh in his mind.
Similarly, being the only one without a title cannot be a good feeling for the Lunatic Fringe, who captured the WWE Championship on his own in 2016.
What Ambrose may do has been a huge talking point, with the only man who knows, is Dean himself.
