The defeat ended Leverkusen’s 12-match unbeaten run and extender Bayern’s lead at the top of the table to 14-points.
But with Jupp Heynckes 1-0 up at the BayArena, Bailey was a matter of inches away from levelling proceedings with a real moment of magic.
Cutting in from the right flank, 20-year-old Bailey skinned Bayern centre back Niklas Sule twice before attempted an audacious curling effort on goal.
His shot had goalkeeper Sven Ulreich beaten all-ends-up, only to be denied by the crossbar.
In an interview with Bild, Bailey admitted that playing in England was a ‘dream’ of his.
