David Wagner was appointed Huddersfield Town's head coach in November 2015, winning promotion to the Premier League in his first full season.
The former forward represented United States eight times but all of his playing career was in Germany where he was born.
In the 1996/97 season, the German won the UEFA Cup with FC Schalke 04 before playing out the rest of his career in the second tier.
Wagner's managerial career currently spans only two clubs, with his first being Borussia Dortmund II.
The German led the club from July 2011 until 1 November 2015.
Four days later, Wagner was announced as the head coach of Championship side Huddersfield Town.
The 2015/16 season ended with the Terriers in 19th place, but an unbeaten start to the following season left Wagner's side top in September.
A play-off place was secured at the end of the season and, after a draw in both legs of the semi-final against Sheffield Wednesday, Huddersfield triumphed in a penalty shootout.
Wagner then led the club to the Premier League for the first time after defeating Reading 4-3 on penalties in the final.
In his first month of managing in the Premier League, Wagner earned the August Manager of the Month award, having guided the Terriers to two victories without conceding and a goalless draw with Southampton.
But he left Huddersfield on 14 January 2019 with the club bottom of the table with 11 points from 22 matches.
