Champions League group stage, Dortmund dropped into the Europa League. On 10 December 2017, Bosz was sacked and replaced by Peter Stöger. Bayer Leverkusen On 23 December 2018, he was appointed as the new head coach of Bayer Leverkusen. After his appointment Leverkusen's form improved significantly leading to Leverkusen securing UEFA Champions League qualification in the final game of the season. Bosz was sacked in March 2021 after the team dropped to sixth place with seven points to direct UEFA Champions League qualification. Olympique Lyonnais On 29 May 2021, Bosz was appointed as the head coach of French side Lyon and signed a two-year contract, replacing Rudi Garcia. On 9 October 2022, Bosz was sacked 10 matches into the season with Lyon in 9th place in Ligue 1. He was replaced by Laurent Blanc. Coaching style Bosz favours an attacking style of play, based on ball possession and aggressive pressing. Furthermore, Bosz's tactical ideas are heavily influenced by the football of Johan Cruyff. As a result of this attacking style, Bosz has changed the positions of many of his players. Bosz won plaudits for his conversion of Lasse Schone, who played on the wing for Frank de Boer into the holding midfield position, utilising Schone's technique to enhance Ajax's build-up play. Furthermore, Julian Brandt, was moved from the position of left-winger under Heiko Herrlich into a central attacking midfield position by Bosz, which resulted in a significant upturn in form. However, Bosz's style does have its detractors. His failure at Dortmund was partly credited to a perceived idealistic attacking approach which left Dortmund continuously vulnerable to the counter-attack.
