Brazil forward Neymar became Paris St-Germain's fourth-top scorer of all time as the French champions held on for a narrow win at home to Brest.
The 30-year-old claimed his 110th goal to move in front of ex-Portugal striker Pauleta on PSG's list of scorers.
PSG were unable to add to their lead and then Brest won a penalty on 70 minutes - but Gianluigi Donnarumma saved Islam Slimani's tame spot-kick.
Victory sent unbeaten PSG back above Lens at the top of the Ligue 1 table.
Lens led Ligue 1 after winning 1-0 at home to Troyes on Friday. Lionel Messi chipped the ball forward for Neymar to score his eighth goal from seven Ligue 1 game this season.
The Brazil forward took a touch with his right foot before firing in with his left.
Zlatan Ibrahimovic is next on PSG's all-time scorers list with 156, while Neymar's team-mate Kylian Mbappe is second with 180.
Christophe Herelle was shown a red card for bringing down Neymar but the decision was overturned as a review showed the PSG forward was offside before the tackle.
Messi and Mbappe spurned chances either side of half-time and looked set to pay for the misses when Presnel Kimpembe committed the foul for the penalty.
However Donnarumma denied Slimani then made another diving save after a cross diverted goalwards off the Brest forward's shoulder.
