ZAGREB: Bayern Munich eased into the Champions League's last 16 after a second-half double by top scorer Robert Lewandowski gave them a 2-0 win at Dinamo Zagreb in their Group F match on Wednesday.

Bayern, who had already secured top spot in the group, finished with 15 points from six games, six ahead of Arsenal, who booked their berth with a 3-0 win at Olympiakos Piraeus.

After a tepid first half, Bayern coach Pep Guardiola brought on Thomas Mueller into his makeshift side at the interval and Germany's 2014 World Cup winner made a telling impact despite missing a 90th-minute penalty.

Mueller's perfect cross allowed Lewandowski to break the deadlock with a diving header on the hour and the Poland striker added the second with a dinked finish three minutes later.

Five times European champions Bayern dominated from the start but Dinamo missed the best two chances in the first half on a chilly night in Zagreb.

Bayern's Sven Ulreich denied El Arabi Hilal Soudani with a superb save before the Algeria striker headed wide after the German side's reserve keeper misjudged an inviting cross by Dinamo's 18-year old midfielder Ante Coric.
