#4 Aiden English
Aiden English played a key part in one of the most over gimmicks in WWE in recent times, Rusev Day when he joined forces with Rusev. But, WWE did not utilize the Rusev Day gimmick to its maximum potential which also saw the end of English on WWE television following a brief feud with Rusev.
The former NXT Superstar's last match on the main roster was back in October 2018, against Rusev, and he hasn't wrestled on WWE TV since. Earlier this year, English became a commentator on 205 Live, a move which could signal the end of his in-ring career.
But English could maybe return soon, with the Rusev-Lana-Bobby Lashley storyline picking up steam on RAW. English commented on Lana cheating on Rusev after a similar angle played out between Rusev-Lana-English last year.
English may not step into the ring to compete in matches, but he could surely add some extra spice into the Rusev-Bobby Lashley feud on the red brand.
