Munich (Germany), Nov. 30, 2019
Bayern, who had won their previous four games in all competitions under Flick, hit the woodwork three times and missed close to a dozen golden chances from top scorer Robert Lewandowski, Serge Gnabry and Ivan Perisic among others.
Leverkusen were left with 10 men after a red card for Jonathan Tah in the 82nd minute and survived enormous pressure to hold on to a memorable win.
The visitors drew first blood in the 10th minute with Bailey, back from a two-game suspension, charging clear to latch onto a Kevin Volland pass and score.
It was another scintillating run by the 22-year-old that put them ahead again, only a minute after Thomas Mueller had drawn the hosts level.
Bayern, who had won the previous six games at home against Leverkusen, dropped to fourth place on 24 points, three behind leaders RB Leipzig who won 3-2 against Paderborn. Leverkusen moved up to seventh on 22 points.
