FC Carl Zeiss Jena 0-5 Bayern Munich

Robert Lewandowski's hat-trick was his first in the German Cup since doing so in the 2012 final - against Bayern Munich - for Borussia Dortmund

Robert Lewandowski scored a first-half hat-trick as Bayern Munich thrashed fourth-tier Carl Zeiss Jena in the first round of the German Cup.

It was Carlo Ancelotti's second game in charge, following Sunday's 2-0 win over Borussia Dortmund in the German Super Cup.

German Cup holders Bayern were 3-0 up at half-time before Lewandowski set up Arturo Vidal for their fourth.

Mats Hummels completed the scoring with his first goal for the club.

Bayern, whose coach Pep Guardiola left for Manchester City this summer, open their Bundesliga defence at home to Werder Bremen on 26 August at 19:30 BST.
