#2 Walter
Walter has been Europe's hottest professional wrestler for a few years now, but given his ability and the resume he put together, many people though there would be a bidding war for his signature, but like always, the WWE got their man. He made his NXT UK debut at Takeover: Blackpool, but despite that limited time with the company, it's clear he's ready to be a top star in the wrestling industry.
It's been said that Walter only wants to work with NXT UK so he can continue to be a coach/trainer for wXw in Germany, but a man this talented needs to be seen by the biggest audience possible.
Walter is big, he has a great presence and hits harder than most professional wrestlers in the entire world, and given how the WWE is lacking in genuine top stars, Walter would make a huge impact on RAW or Smackdown, and if the WWE can convince him to change his mind, he'll be a main event player in no time.
