#4 Andrade Cien Almas
Andrade Cien Almas is, without a doubt, the most outlandish pick on this list. Almas debuted in the main roster on 15th May 2018 and since then, his appearances on WWE TV have been sporadic, to say the least, resulting in the lack of any lasting feuds.
However, his matches with AJ Styles, Daniel Bryan and Rey Mysterio have all shown his in-ring capabilities. The mere fact that Almas has been given opportunities to compete with top stars of Smackdown Live even in his limited appearances shows that the WWE upper management has immense faith in the potential of Andrade Cien Almas as a main event star.
Almas has had a wonderful 2018 with his epic title bout with Johnny Gargano at NXT Takeover: Philadelphia garnering overwhelming praises from everyone (the match received a 5-star rating from prominent wrestling journalist, Dave Meltzer). Keeping these in mind, WWE might be swayed to give Almas a big push without any further ado by putting him directly into the WWE Championship picture.
