David Wagner has been Huddersfield Town's head coach since 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 he left the club on 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, which consisted of a penalty shootout victory over Sheffield Wednesday after a draw in both legs.
Wagner then led Huddersfield to the Premier League for the first time after defeating Reading 4-3 on penalties.
