Atletico Madrid tasted defeat in the Champions League for the first time this season as Robert Lewandowski's free-kick secured a 1-0 win for Bayern Munich at the Allianz Arena on Tuesday.
The Poland international's goal in the first half settled the contest in the home team's favour, but Atletico, last season's beaten finalists at the hands of cross-city rivals Real Madrid, will still advance to the round of 16 as winners of Group D, having recorded five victories from six matches played.
Bayern, who exited the 2015-16 competition at the hands of Diego Simeone's team in the semi-finals in April, were forced to settle for second spot and a potentially difficult assignment in the first knockout round, as the Bundesliga title-holders continue their search for consistency under Carlo Ancelotti.
Their performance here will at least be of some comfort to the Italian, who watched his players control the contest, albeit against a visiting team likely to have placed more importance on a trip to Villarreal on Monday, as they seek to make up ground on Sevilla, Barcelona and leaders Madrid in LaLiga.
For Bayern, attention will now turn to the visit of Wolfsburg this weekend, with the indignity of trailing surprise league leaders RB Leipzig weighing heavily on German football's dominant force.
Douglas Costa issued the hosts' first real warning shot when he called Jan Oblak into action at the goalkeeper's near post following good work from Renato Sanches.
