Bayern Munich suffered a heavy defeat as Eintracht Frankfurt beat them 5-1.The German champions defender Jerome Boateng was sent off after nine minutes of the game which cost Bayern a heavy defeat at Frankfurt.
Filip Kostic and Djibril Sow put the hosts 2-0 ahead, but Robert Lewandowski responded for Niko Kovac’ side with his 14th league goal of the campaign.
David Abraham made it 3-1 shortly after half-time, before Martin Hinteregger and Goncalo Paciencia added the gloss.
Defeat leaves Bayern four points behind leaders Borussia Monchengladbach.
RB Leipzig’s 8-0 thrashing of Mainz and Borussia Dortmund’s 3-0 win over Wolfsburg also see Niko Kovac’s side slip to fourth.
Bayern Munich faced an uphill battle after Boateng was dismissed for bringing down Paciencia following a swift Frankfurt counter.
Despite their numerical disadvantage Bayern enjoyed 61% of the possession, and Lewandowski’s 20th goal in all competitions this season offered an unlikely lifeline at the interval.
But a direct and clinical Frankfurt side dismantled their tiring opponents in the second half – and the score would have looked even more emphatic had it not been for some fine goalkeeping by Manuel Neuer.
