Lewandowski notches another hat-trick in Bayern's DFB-Pokal opener

Berlin - Robert Lewandowski netted a hat-trick Friday as DFB-Pokal holder Bayern Munich brushed past minnow Carl Zeiss Jena with a 5-0 away win in the first round of the competition.

The Poland striker put Bayern ahead after just three minutes at fourth-division club Jena, the former East German champion that's fallen from grace, combining with Thomas Muller before slotting home.

Lewandowski then tapped in from close range after Franck Ribery's pass found him in the area on 34 minutes.

He rolled another shot past Jena goalkeeper Raphael Koczor nine minutes later to claim his third and leave Bayern 3-0 up at the break.

Chilean midfielder Arturo Vidal netted the fourth, converting Lewandowski's final pass on 72 minutes having twice hit the woodwork.

Centre-back Mats Hummels then bagged his first goal for Bayern with a late header.

The cup tie had the air of a competitive training session for Bayern. Manager Carlo Ancelotti fielded a full-strength side that had played international football in the close season.

Bayern opens the new Bundesliga season next Friday when the defending champion hosts Werder Bremen.

The Bavarian giant is chasing a fifth consecutive domestic title, with Ancelotti having succeeded Pep Guardiola on the bench.
