An injury-time header from Patrik Schick helped Bayer Leverkusen to a come-from-behind 4-3 win at Stuttgart on Sunday, taking the defending Bundesliga champions to within six points of leaders Bayern Munich.
Bayern's 1-1 draw at Union Berlin on Saturday left the door slightly ajar for Leverkusen but Xabi Alonso's side looked down and out, having trailed for almost the entire match on Sunday.
Leverkusen, missing injured talisman Florian Wirtz, fell behind after 15 minutes.
Nick Woltemade found Jamie Leweling whose shot was blocked by Leverkusen goalkeeper Lukas Hradecky, but Ermedin Demirovic was on hand to knock the ball in.
