Midfielder Seb Amoros has announced on Facebook that he is leaving the club.
The French midfielder joined on a one-year contract with the option for a further year.
However, in a Facebook post he commented: “I post this picture to tell you that I won’t be a Vale player for the next season. I really want to say a massive thanks to all the Vale fans because you gave me a lot of support! I’m proud to have worn your colours!
He made ten appearances for the club during an injury-disrupted season.
