PARIS (AP) -- Substitute Kevin Gameiro scored in injury time to give 10-man Paris Saint-Germain a crucial 2-1 win at Dijon in its bid to win the French title for the first time since 1994.
PSG was a player down for the entire second half, after midfielder Mohamed Sissoko -- returning from a suspension -- was sent off in the 40th minute, but took the lead shortly after the break through defender Siaka Tiene.
Defender Steven Paulle equalized for Dijon in the 75th and Gameiro, who came on for Guillaume Hoarau shortly after, provided the winner in the first minute of injury time.
"It's a very important win for us tonight. We won a very difficult match at the end with 10 players. The team showed fantastic character, we were mentally very strong," PSG coach Carlo Ancelotti said. "I'm very happy because we're still on the top of the league and this win will give us confidence for the future."
Gameiro recently lost his place in the starting lineup, but Ancelotti is bringing the best out of his forwards by increasing competition for places.
"This win shows that we're counting on everyone to succeed, including the players who are on the bench," said Gameiro, who is also vying with Hoarau for a place in France's squad for the European Championship, which starts in June. "Montpellier won't give up but if we don't drop any points we won't have to look behind."
PSG moved provisionally four points ahead of Montpellier, which was playing at home against Caen later Sunday.
France winger Jeremy Menez created PSG's opening goal, pulling the ball back to give Tiene's first league goal for the club. But sloppy marking in PSG's defense was again exposed when Paulle headed past goalkeeper Salvatore Sirigu to make it 1-1.
"Of course I'm happy to have scored, but the team is more important than anything else," Tiene said. "We'll give everything we have in each match to take maximum points until the end of the season. The race for the title is still long."
Dijon was pressing for a winning goal from a corner, only for PSG to counterattack and Gameiro to grab his 11th league goal of the season after Menez sprinted from the halfway line and set him up on the edge of the penalty area. Menez's pass wasn't cushioned enough, and Gameiro did well to snap the ball down and rifle it into the corner without breaking stride.
"Above all, we must not get carried away with this," Menez said. "We still have 11 matches left."
Also, Rennes drew 1-1 at home to Auxerre. Kenya forward Dennis Oliech put the visitors ahead early on, but midfielder Yacine Brahimi equalized midway through the second half for Rennes.
