Bayern Munich are planning an inquest into the two goals they conceded against Eintracht Frankfurt, with Hansi Flick calling for a clean sheet against Borussia Dortmund on Tuesday.
Thanks to goals from Leon Goretzka, Thomas Muller and Robert Lewandowski, Bundesliga leaders Bayern looked comfortable with a 3-0 lead after 50 minutes at the Allianz Arena on Saturday.
However, they were caught napping at two set-pieces in the space of three minutes, with Hinteregger allowed space to bundle a volley past Manuel Neuer before powering a header into the back of the net.
