Not just BVB though. Tuchel at Mainz:
He was named as the new head coach of 1. FSV Mainz 05 on 3 August 2009, after the club was promoted to the Bundesliga. He had been a youth team coach for Mainz for the previous 12 months. He signed a two-year contract after being promoted to that position from the 1. FSV Mainz 05 Under 19 side.
In the 2010–11 season, Tuchel coached Mainz to seven wins in their first seven games, including an away victory over Bayern Munich. The team finished fifth in the rankings. Schalke 04 and Bayer Leverkusen both made approaches for Tuchel in the latter–half of the 2013–14 season. Tuchel led Mainz to a 2014–15 UEFA Europa League spot during the 2013–14 season after finishing the season in seventh place. Tuchel asked to be released from his contract prematurely. Tuchel left the position of head coach on 11 May 2014. However, Mainz refused to release him from his contract. He finished his Mainz career with a record of 72 wins, 46 draws, and 64 losses. Tuchel later said of his decision to leave the club: "I couldn’t see how we could reinvent ourselves once more the coming summer."
