#4 Netherlands - Aleister Black

Aleister Black is WWE's only Dutch superstar today. The former Tommy End had a successful career in the UK independent circuit. He has won several Championships as well including the Progress and ICW Tag Team Championships.
Black was signed by WWE in 2016 and he made his debut as a mysterious character who rarely spoke. He was an instant hit with the crowd and had an amazing feud against Velveteen Dream. He won the NXT Championship from Andrade Cien Almas and eventually lost it to Tomasso Ciampa earlier this year. He got injured before he could get his rematch.
Black recently returned from his injury and participation in the World Cup alongside a NXT Championship rematch can really do wonders for his career.
