Jurgen Klopp’s former assistant at Borussia Dortmund has rejected an approach from Liverpool to become the new Huddersfield manager.

David Wagner is set to replace Chris Powell as manager in an ambitious move by the Championship strugglers. His appointment is set to be confirmed in the next 48 hours.

Liverpool had targeted Wagner to join Klopp’s new-look back-room staff after his departure from Dortmund this week but he will instead succeed Powell, who was sacked on Wednesday.

Wagner, 44, worked closely with Klopp at Dortmund and was even the Liverpool manager’s best man at his wedding. And though Zeljko Buvac and Peter Krawietz have both joined Klopp at Anfield, the lure of a No. 1 job has proven too attractive to turn down for former USA international Wagner.

During his time in charge of Dortmund’s under-23s, he established an impressive reputation for the same high-intensity, pressing style of play that Klopp became renowned for.

Huddersfield’s chief executive Nigel Clibbens and head of football operations Stuart Webber are thought to be behind the appointment and Wagner will watch Saturday’s Yorkshire derby against Leeds from the stands.

Powell’s year-long reign was ended today, less than 24 hours after the 2-2 draw at Reading.

Powell becomes the fifth Championship manager to leave his club this season, joining Marinus Dijkhuizen, Steve Evans, Uwe Rosler and Guy Luzon. He was appointed last September and guided Huddersfield to 16th in his first campaign.

Tuesday night’s 2-2 draw at Reading leaves them 18th in the Championship.
