Brighton boss Graham Potter has no doubts Davy Propper is a target for bigger clubs.
Propper is now on a deal until June 2023.
Potter told The Argus: “I don't know but I would imagine so and not just in the Premier League but across Europe.
“He is in the Dutch side, playing in midfield in that team alongside and in front of some really good players.
“He is a talented footballer and a top professional as well.
“He is a man of few words but, when he does speak, he speaks intelligently and he works hard for his career."
