Hansi Flick joined Bayern Munich on 1 July 2019 as an assistant coach. Under Kovač, Bayern was off to a slow start in the league and after a 5–1 loss to Frankfurt, Kovač and Bayern parted ways on 3 November 2019 with Flick being promoted to interim manager. After a satisfying spell as interim coach, Bayern announced on 22 December 2019 that Flick would remain in charge until the end of season. Bayern's performances on the pitch picked up noticeably and in April 2020, the club agreed with Flick to a new permanent contract through 2023. Under Flick the club won the league, having played the most successful leg of a Bundesliga season in history, and went on to claim the cup, thus completing the club's 13th domestic double. In the Champions League, Bayern reached their first final since 2013, en route beating FC Barcelona 8–2 in the quarter-finals and Lyon 3–0 in the semi-final. In the final, which was held in Lisbon behind closed doors due to the severity of COVID-19 pandemic, they defeated Paris Saint-Germain 1–0. Former PSG player Kingsley Coman scored the only goal of the match. With the victory, they became the second European club to complete the continental treble in two different seasons, matching the 2014–15 FC Barcelona team.
