Frankfurt 5-1 Bayern: Kovac's side suffer a disastrous defeat after Boateng red

Bayern Munich failed to recover from an early Jerome Boateng red card as they fell to a 5-1 defeat against Eintracht Frankfurt that will heap more pressure on beleaguered coach Niko Kovac.

The pressure has been building on Kovac and his side shipped five more goals on a day that saw Thomas Muller make his 500th appearance for the club.

Filip Kostic and Djibril Sow scored their first goals of the season to punish the champions after Boateng was sent off inside nine minutes.
