#2 Pete Dunne
Pete Dunne was a superstar from the moment he faced his first opponent in the inaugural WWE UK Championship Tournament. He didn't win the tournament but with his in-ring work and heel persona, he looked ready for NXT or main roster at that time.
However, nothing substantial followed the tournament. As all the talented guys from the UK roster wandered around for random matches, but the popularity of Pete Dunne only increased and after a stellar match against Tyler Bate in NXT TakeOver: Chicago, he won the WWE UK title.

Dunne Debuted on the main roster against Enzo Amore and squashed him in a short match, unfortunately, that was not a proper call-up but just a ploy to make the home crowd happy. Currently, Dunne is performing more frequently in weekly NXT programming and house shows that means WWE knows his worth and working on his actual main roster call-up.
