#4 Shinsuke Nakamura
When Shinsuke Nakamura joined WWE, it took over the internet. Fans were happy to hear that the NJPW megastar is now coming to WWE but since arriving on the main roster, Nakamura has only disappointed his fans.
He won 2018 Royal Rumble match but failed to win the WWE Championship at WrestleMania. He turned him and it was a major hit to his career. He has now lost all of his momenta and I don’t think WWE could revive him easily.
However, in WWE, things change in the snap of a finger. Kingston gained popularity after his amazing performance on SmackDown Live and Elimination Chamber so why can't Nakamura?
He, too, provides great matches and his bout against Kingston could also help him in becoming relevant again.
