Defending champions Paris St-Germain lost their hastily re-arranged Ligue 1 game away to Marseille, which ended with home manager Roberto de Zerbi being sent off in stoppage time.
Former West Ham defender Nayef Aguerd’s fifth-minute header proved to be the winner in a fixture which had been postponed by a day because of forecasts of heavy rain and storms.
It was PSG’s first Ligue 1 defeat of the season.
“We are not used to losing games,” said PSG boss Luis Enrique, who was named coach of the year at the Ballon d’Or awards, held at the same time as the match.
The French champions were also without injured forward Ousmane Dembele, who stayed in Paris to attend the Ballon d’Or awards, where he won the main men’s prize.
Marseille started brightly, striking early as Aguerd headed in at the far post after PSG goalkeeper Lucas Chevalier completely misjudged Mason Greenwood’s cross.
While the visitors looked to respond, Marseille nearly doubled their advantage, with Amine Gouiri hitting the crossbar.
Marseille goalkeeper Geronimo Rulli made several key stops, including a sharp save from Achraf Hakimi, while PSG striker Goncalo Ramos headed over a golden chance to level after half-time.
Tensions flared late in the game, and Marseille’s former Brighton boss De Zerbi was sent off in stoppage time.
Marseille are sixth in the table with nine points from five games, while PSG are second on 12 points.
