Jan Siewert
Huddersfield tried to repeat the success they had with David Wagner by appointing their second manager who had previously taken charge of Borussia Dortmund’s reserve team.
Unfortunately, this time things didn’t go quite as swimmingly, with Siewert winning just one of his first 15 league games in charge of the Terriers, with the Yorkshire club being relegated from the top flight. He was subsequently sacked after a poor start to the season in the Championship.
