The German playmaker is out of contract this summer but Albion head coach insists his key man is close to agreeing a new deal.
Gross, 30, singed off the campaign with another performance against West Ham and netted a fine goal during the 3-1 victory against David Moyes’ men on the final day of the season.
Gross has been a vital addition to the Albion squad when they were promoted to the Premier League in 2017.
He joined from Bundesliga outfit Ingolstadt for just £2.5m and quickly established himself in the top flight.
Speaking after the West Ham win, Potter said: “The manager added, “I think it is relatively done.
"I think it is just formalities at the moment to get things done but he is happy here, we are happy with him, he has got a fantastic relationship with the supporters, he is a legend.
"I would say a Brighton legend in terms of the Premier League.
"What he has given to the club is fantastic and we want him to stay.”
