Paris Saint-Germain underlined their superiority over the rest of the French top flight on Sunday as Zlatan Ibrahimovic netted twice in a 4-0 win against Lyon at the Parc des Princes.
Ibrahimovic scored both of his goals from the penalty spot as he moved clear at the top of the Ligue 1 scorers chart, while South Americans Edinson Cavani and captain Thiago Silva also found the target to help PSG continue their unbeaten record in all competitions this season.
They finish the weekend in exactly the same position as they started it, four points clear of Lille and five ahead of Monaco at the top of the table, after easing past a Lyon side who once dominated the French scene themselves but who are currently languishing in mid-table.
Alexandre Lacazette had been left to plough a lone furrow up front for Lyon and he had the visitors' best opportunity of the first half, creating space for himself inside the box and lashing a shot against the bar.
But, crucially, PSG got their noses in front nine minutes before the interval, when Cavani met a corner from the left and headed in through the legs of Yoann Gourcuff, who was standing on the near post.
Five minutes later, the Uruguayan was brought down again inside the box. This time, Lyon goalkeeper Remy Vercoutre was the culprit, and this time a penalty was awarded.
Ibrahimovic sent Vercoutre the wrong way as he coolly chipped into the net, and Lyon's chances of getting back into the game appeared to be over by the interval.
They conceded again on the hour mark, captain Silva lashing home the loose ball following a corner for his first ever goal in Ligue 1.
And there was more pain to come for the visitors as Ibrahimovic beat Vercoutre from the spot once again after being fouled by Samuel Umtiti, taking his tally to 20 goals in his last 13 games for club and country.
PSG are now unbeaten in 26 Ligue 1 games and maintain a safe distance from Lille, who won 1-0 at northern neighbours Valenciennes on Saturday as Nigerian goalkeeper Vincent Enyeama extended his remarkable run without conceding a goal to 945 minutes.
Elsewhere on Sunday, Mickael Landreau equalled fellow goalkeeper Jean-Luc Ettori's record of 602 appearances in France's top flight as he kept a clean sheet for Bastia in a 2-0 win over Evian.
The 34-year-old French international began his career at Nantes in 1996 and won the title with Les Canaris in 2001 before spells at Paris Saint-Germain and Lille, with whom he won the double in 2011.
