Bayer Leverkusen came from behind to beat Bayern Munich 3-1 and land another damaging blow against the champions’ Bundesliga title defence.
Ex-Borussia Dortmund head coach Peter Bosz did his former club a huge favour despite Leon Goretzka giving Bayern a 41st-minute lead.
Leon Bailey launched a fabulous free-kick into the top-left corner before Kevin Volland and substitute Lucas Alario sealed victory for a vibrant Leverkusen, who move up to seventh in the table.
Instead of being punished for their 1-1 draw at Eintracht Frankfurt, Dortmund’s lead over Bayern at the summit edges up to seven points.
