#4 Dean Ambrose

Dean Ambrose's heel turn has been a flop so far, and while many of us are huge Ambrose fans, the truth is that Ambrose's turn to villainy has been a comical failure, as WWE messed up the core factors of what his character supposed to be.
Generic motivations, confusing actions, lame promos, and disappointing matches has plagued Ambrose's once promising character shift. But if there were one thing that would have got Ambrose the chance to rebuild his character it would have been a match with the World Champion.

Lesnar vs Ambrose is a match that disappointed a few years ago, but WWE had a clear chance to rectify that error, as Ambrose needs a huge angle to rejuvenate himself right now, and maybe this could have been it.
#5 Finn Balor

Finn Balor is a dark horse on Raw, as no one knows when he can get an opportunity and finally take it, and with the announcement of the new era, WWE could be looking to making Balor a main event star once again.
As rumours suggest Balor is in line for a push from WWE, and what better what way to get the man back on the credible side of things than to put him up against the biggest star on the roster. While Lesnar vs Balor may be a mismatch in term of size and strength, Daniel Bryan and AJ Styles proved that Lesnar could have a great match with a smaller opponent.
