MUNICH (AP) — Bayern Munich began the defense of its Champions League title with a comfortable 3-0 win at home to CSKA Moscow on Tuesday.

David Alaba opened the scoring with a free kick in the fourth minute, Mario Mandzukic headed Bayern's second in the 41st, and Alaba set up Arjen Robben to seal the victory in the 68th.

Bayern, which appointed Pep Guardiola as coach after claiming an unprecedented treble last season, rarely looked troubled by the Russian league leader.

CSKA substitute Georgi Milanov came closest for the visitors in the 82nd, when his 22-meter effort landed on the roof of the net.

Bayern is attempting to become the first club since 1990 to defend the European Cup.

Czech champion Viktoria Plzen lost 3-0 to Manchester City in Group D's other match.
