Paris Saint Germain rode their luck to wrest back top spot in the French league from Lyon on Sunday - an own goal from Cameroon defender Aurelien Chedjou enough to land three points against Lille at Parc des Princes.
Chedjou was the villain of the piece for the visitors, who might easily have taken a point had he not deflected home a loose ball after Lille keeper Steeve Elana parried a cross from Ezequiel Lavezzi midway through the second half.
Carlo Ancelotti's men could have had more goals as Swedish striker Zlatan Ibrahimovic hit the post with a sweetly-struck effort while another effort from the same player stretched Elana.
But Lille also had cause to feel hard done before the break as Ronny Rodelin appeared to have opened the scoring from a corner kick - only for colleague Nolan Roux to be given offside.
Television replays suggested the referee's call was harsh as PSG survived to stand clear of Lyon on goal difference with both clubs on 45 points from 22 games, three ahead of Marseille.
After Tulio de Melo had hit the woodwork in another scare for the home fans PSG held out, which was a boon for Italian keeper Salvatore Sirigu, who during the game set a club-record of minutes without conceding a Ligue 1 goal.
After the opening 12 minutes, Sirigu passed the mark of 697 minutes set by former France international shot-stopper Bernard Lama back in 1996 and his clean sheet stretched the record by another 78 minutes.
Sirigu last conceded a goal in the 35th minute of a November 17 loss to Rennes and he has since kept his net clean seven times.
The overall French record belongs to former Bordeaux keeper Gaetan Huard, who in 1993 was unbeaten for 1176 minutes - more than 13 matches.
