Luis Diaz’s double helped 10-man Bayern Munich maintain their perfect start to the season at the expense of defending European champions Paris St-Germain.
The German side made it 16 successive wins in all competitions, including four out of four in the Champions League to top the league phase table.
Diaz had a mixed night, scoring twice to put Bayern in control before being sent off on the stroke of half-time following a rash challenge from behind on Achraf Hakimi that led to the PSG full-back in tears as he was helped off with a serious-looking ankle injury.
In a chaotic first half at Parc des Princes, Vincent Kompany’s side showed a bravery and willingness to press high up the field, which paid dividends when Diaz hit the opener in the fourth minute.
Ousmane Dembele thought he had levelled midway through the half with PSG’s first shot of the game when he chested in from close range, but his effort was ruled out for offside.
The Ballon d’Or winner then left the field with what appeared to be a calf injury moments later.
Bayern continued to ask questions of the hosts and were desperately unlucky when Serge Gnabry’s shot crashed off one post and on to the other.
But Diaz struck his second in the 32nd minute after stealing possession from a slack Marquinhos and coolly finishing.
The Colombia winger, though, was dismissed just before the break for his tackle on Hakimi. A yellow card was upgraded to a red following a review from the video assistant referee (VAR), with the Moroccan clearly upset.
PSG threw everything at Bayern in the second half, but constantly came up against a brick wall and looked like they weren’t going to find a route back into the encounter.
But with 16 minutes remaining, substitute Joao Neves stole half a yard of space to hit a bicycle kick beyond Manuel Neuer.
That effort reignited PSG and Neuer faced a barrage of shots in the closing stages, making several fine saves to deny Neves, Warren Zaire-Emery and Vitinha.
But the holders suffered their first defeat of this season’s competition.
