Sergio Ramos picked up a straight red card as tempers flared shortly before halftime but a reshuffled PSG, in the absence of the injured Lionel Messi, managed to keep a clean sheet.
Ramos, however, picked up a yellow card after arguing with referee Pierre Gaillouste, who an instant later went back to the Spaniard and handed him a straight red card. Earlier, Marseille’s second place was under threat on Saturday as they were outfoxed by promoted Ajaccio. Third-placed Lorient will leapfrog them into second place if they beat Brest and fourth-placed RC Lens will also move ahead if they grab all three points in the northern derby at Lille on Sunday.
