Micky Adams has made striker Ben Williamson and midfielder Ryan Burge his first signings of the summer.
Both players arrive from non-league Hyde, the English partner club of Glenn Hoddle’s Academy, which is based in Spain.
Adams told the official Port Vale website: “Both Ryan and Ben are two young players with a lot of potential. We believe the pair can have a big impact on the squad this season.
“Ryan is a creative central midfielder and will bring plenty of quality on the ball, but he is also a very hard-working individual.
“Ben is a quick striker who I have been tracking for a while and I believe is a player who can develop with us.”
