On 28 July 2015, Vidal returned to the Bundesliga, joining Bayern Munich on a four-year deal for a fee of €37 million plus up to €3 million in bonuses. Vidal made his debut for Bayern four days later in the 2015 DFL-Supercup against VfL Wolfsburg, as a 74th-minute substitute for Thiago. The match finished in a 1–1 draw; Bayern lost in a shootout where Vidal scored. Vidal scored his first goal from the penalty spot in the fifth minute of Bayern’s first round DFB-Pokal match. On 26 November, Vidal was nominated for the 2015 UEFA Team of the Year.
