Trossard believes that many changes will happen next season under Potter, who is known for preferring a more expansive playstyle.
The Genk captain is set to complete a move to the Seagulls for a near-£18 million fee.
He told Flemish TV network VTM Nieuws: "I have a good feeling with Brighton.
"I had a good conversation with Graham Potter. He wants to play attacking football.
"It's a club that can offer me a lot of minutes."
