Port Vale assistant manager Mark Grew expects Anthony Griffith to catch the attention of clubs from higher divisions.
Montserrat international Griffith is an ever-present for the League Two club this season.
The 24-year-old moved to Vale Park on a free transfer from Doncaster in 2008 and celebrated his 150th appearance for the club with just his second goal against Northampton on Friday.
Griffith scored the second - a stunning 35-yard effort - in a 3-0 home win.
"People say he's only got strength and tackling ability, but on the ball he's three times better than he was," Grew told BBC Radio Stoke. "He's worked hard at his game. I think there will be a lot of clubs interested in him just for that work ethic.
"Both he and Sam Morsy are out every afternoon working on their passing. He knew when he came here that he was limited in some things and to get them right, and you have to go out onto the training pitch and work hard at it."
