Bayern Munich made a grand statement in the UEFA Champions League as they hammered Barcelona 8-2 to book their semi-final place in remarkable fashion.
Lionel Messi and his team-mates were swept aside by the dominant Bundesliga champions in a chaotic first half, with Philippe Coutinho then coming on to deal further blows to his parent club in the closing stages.
Thomas Muller's sublime strike got things started and, although David Alaba's own goal drew Barca level, Ivan Perisic and Serge Gnabry had Bayern 3-1 up by the 27th minute.
Muller's second piled further misery on Barca – who conceded four goals in the first half of a Champions League match for the first time – and while Luis Suarez responded after the break, Bayern had more to give.
Joshua Kimmich restored a three-goal cushion with a goal set up by the brilliance of Alphonso Davies, before Coutinho set up Robert Lewandowski and helped himself to a double within the space of seven minutes to compound the misery of the club that owns him.
It took Bayern four minutes to hit the front as Lewandowski teed up Muller, whose side-footed volley found the bottom-left corner.
Yet Bayern's lead lasted just three minutes – Alaba slicing an attempted clearance in over Manuel Neuer.
The chaos continued as a Messi cross hit the post, but Bayern restored their lead in the 21st minute as Perisic thumped home from an acute angle – Gnabry then drilling in a third.
Muller swiftly gave Bayern their fourth, tucking in from Kimmich's cross, while Lewandowski had a goal disallowed after the restart.
Suarez pulled one back for Barca before the hour, but any comeback hopes were soon extinguished as Davies raced beyond the hapless Nelson Semedo to tee up Kimmich.
Substitute Coutinho then stole the show with a brilliant cameo, first crossing for Lewandowski to head home, with the goal standing despite a strong hint of offside.
Coutinho made it 7-2 with a crisp low finish three minutes later, and the Barca loanee had the final say with a close-range effort on the turn to cap an incredible match and one of the darkest days in the Blaugrana's history.
