Robert Lewandowski scored a hat-trick in Carlo Ancelotti’s first league match in charge as Bayern Munich thrashed Werder Bremen in the opening game of the Bundesliga season.
The champions went ahead through a stunning Xabi Alonso volley before Lewandowski struck twice.
Captain Philipp Lahm and Franck Ribery also netted, and Lewandowski converted a penalty after Thiago was fouled.
Thomas Muller assisted with three of the six goals at the Allianz Arena.
Defender Mats Hummels, who joined from Borussia Dortmund in the summer, played the full 90 minutes, while 19-year-old midfielder Renato Sanches, a £27.5m signing from Benfica, was an unused substitute.
Ancelotti, who took charge following Pep Guardiola’s summer departure for Manchester City, won the German Super Cup this month.
