Huddersfield manager David Wagner and his coaching team have signed new three-year contracts, the Premier League club have announced.
Wagner, assistant Christophe Buhler and first-team coach Andrew Hughes will remain at the John Smith's Stadium until the summer of 2021.
The trio had 12 months left on their previous contracts and the new deals end months of speculation over their future, with various clubs reported to have been keen to appoint them.
"The decision to extend my stay at this club was not a difficult one," Wagner said. "The relationship Christoph, Andy and I have with [chairman] Dean [Hoyle], 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."
Hoyle said he had always remained confident that Wagner, who steered Huddersfield into the top flight last year and kept them there, would commit himself to the club.
"He's played a huge role in transforming Huddersfield Town into the club it is today," he said.
"We have a fantastic working relationship and we're looking forward to taking on the challenge of establishing Huddersfield Town in the Premier League together."
