Huddersfield head coach David Wagner has signed a three-year contract extension with the club, until the summer of 2021.
Assistant head coach Christoph Bühler and first-team coach Andrew Hughes have also agreed to remain at the John Smith’s stadium for the next three seasons.
In a club statement, Wagner, who guided the club to Premier League safety this season, said: “The decision to extend my stay at this club was not a difficult one.
“The relationship Christoph, Andy and I have with Dean, the rest of the board, the staff and the supporters is special. We’ve achieved some incredible things together in two and a half years and now I’m excited about the future.
“We still have a lot of work to do as we adapt to life in the Premier League, but this club and its people have the ambition, desire and attitude to take this challenge on.
“Finally, a message to Huddersfield Town fans everywhere. Thank you for the support you have shown us and the players since I joined the club; it’s been such a big factor in the success we’ve enjoyed.”
Wagner, who joined the club from Borussia Dortmund II in 2015, took the club to the Premier League for the first time in its history after securing promotion with a win in the Championship play-off final against Reading in 2017.
During his first season in the top flight, Wagner narrowly avoided relegation with Huddersfield finishing the campaign four points clear of the drop zone.
Huddersfield Town chairman Dean Hoyle added: “I’m very happy that we can announce David, Christoph and Andrew’s new contracts today on the back of a superb debut Premier League season.
“I understand why David is so talked about and sought-after given the things he has achieved here; he’s a very talented head coach and has played a huge role in transforming Huddersfield Town into the club it is today.”
