Brighton have handed Graham Potter a six-year transfer extension.
The Englishman only joined Albion from Swansea City six months ago.
But the Seagulls are impressed with their new manager and have rewarded him in kind.
"We've been really pleased with the start Graham has made as head coach since joining us in the summer, and I'm delighted he and his staff have committed to these new long-term contracts," Brighton chairman Tony Bloom said.
"Together with his backroom team, he has continued the club's progress of recent years and brought a different approach with a new style of play, which has been embraced by players and supporters alike.
"In the summer we unveiled a new long-term vision for us to become an established top-10 Premier League club, and we feel even more strongly that Graham as a bright, energetic and innovative head coach, is the right man to lead us there."
