On 5 August 2017, Ancelotti started the 2017–18 season with Bayern Munich by retaining the DFL-Supercup, beating out Borussia Dortmund 5–4 on penalties, following a 2–2 draw after 90 minutes; this was the sixth time that Bayern had managed to win the title. However, on 28 September 2017, Ancelotti was sacked as manager of Bayern Munich, following a 3–0 away loss to Paris Saint-Germain in the club's second group match of the 2017–18 Champions League the night before. After the Paris Saint-Germain match, reports surfaced that Ancelotti had lost the dressing room. It was reported that five senior players wanted Ancelotti out as manager which Bayern's president Uli Hoeneß later confirmed. Questions were also raised about Ancelotti's tactical setup and team selection against Paris Saint-Germain when he left several key players on the bench and one was left to watch the match from the stands.
