#4 Roman Reigns
I know Roman can be a polarising figure in the WWE but he has shown himself to be a quality hand throughout the last year. Seriously, think of a bad match he has had on a pay-per-view stage. He may not always be booked the proper way on Raw but you cannot deny his in-ring skill.
This would make him a credible looking threat to Goldberg at WrestleMania.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
Based on his booking, it seems quite clear that Roman is clearly regarded as the face of the company to build around in the coming years. Whether it is as a good guy or a bad guy, Roman will be near the top of the roster. He simply needs more big-time matches to get to that point.
With matches with Triple H, Brock Lesnar and Goldberg under his belt, you cannot deny that it would push Roman as a major player for each WrestleMania season going forward.
