Goncalo Ramos scored an injury-time winner as Paris St-Germain won at Barcelona in a meeting of two of the Champions League favourites.
Barcelona led when Ferran Torres slid in to meet Marcus Rashford's fine low ball from the left.
England's Rashford has scored or assisted a goal in five of Barcelona's last six games.
But European champions PSG levelled when Nuno Mendes found Senny Mayulu after a good run and the 19-year-old slotted home.
The visitors, who were missing players through injuries, had the best chances to win the game, and managed to do so with Ramos' first-time finish from Achraf Hakimi's cross.
It takes them to six points from two games, with Barca on three.
