René Müller

SC Paderborn 07

Müller began his coaching career in November 2011, when he was appointed manager of Landesliga club TuS Tengern. He left the position in June 2012, to join SC Paderborn 07 as manager of the club's youth academy and head coach of the U23/reserve squad. On 5 May 2013, Müller took over as interim coach of SC Paderborn's professional team for the rest of the season, following the dismissal of Stephan Schmidt. He was then replaced by André Breitenreiter at the end of the season. At the end of December 2013, Müller once again took charge of the U23 team, this time on interim basis until the end of the season, beside his position as manager of the club's youth academy. After the season, he only continued with his duties as academy manager. On 6 October 2015, Müller once again took charge of Paderborn's professional team on interim basis, following the departure of Markus Gellhaus. Müller was replaced on 13 October 2015 by Stefan Effenberg and continued his duties as academy manager. However, on 3 March 2016, Müller once again took over Paderborn's first team as the new head coach following the dismissal of Stefan Effenberg. Müller was, however, unable to prevent the team's relegation to the 3. Liga. In November 2016, he was released; Paderborn was in 17th place in the table at the time.
