Zlatan Ibrahimovic scored a controversial penalty as Paris Saint-Germain snatched a 1-1 draw at Ligue 1 leaders Lyon on Sunday.

Champions PSG could have gone top with victory but needed a highly contentious retaken penalty just to earn a share of the spoils at the Stade Gerland.

They remain third, two points behind their night's hosts, and level with second-placed Marseille, who drew 1-1 at Rennes on Saturday.

Swedish giant Ibrahimovic saw his first penalty attempt saved by goalkeeper Anthony Lopes, but he had another chance seconds later when the referee decided Lyon players had encroached on the penalty area too early.

This time he made no mistake, equalising in the 69th minute.

With Ligue 1 top scorer Alexandre Lacazette out injured, the young Lyon side held its own thanks to a fine performance from Lopes.

They even took a surprise early lead through Cameroon youngster Clinton N'Jie on 31 minutes, his second goal of the season, following a clever one-two with Nabil Fekir.

Ibrahimovic, Edinson Cavani and David Luiz all failed to convert chances, leaving coach Laurent Blanc frustrated.

Blanc will be left scratching his head trying to find an answer as to how his side managed to fail to win a match in which they dominated possession and created the lion's share of chances.

Lyon could even have extended their lead late on but Fekir and Arnold Mvuemba missed good chances.

And the leaders will feel hard done by after that re-taken penalty, despite maintaining their advantage at the top of the table.

Earlier, Monaco's recent charge up the standings came to a shuddering halt when they conceded a first goal in over 800 minutes to fall 1-0 at ten-man Guingamp.

The result leaves Monaco fifth on 40 points while Saint Etienne, who drew 3-3 with Lens on Friday, have 41 in fourth, but only the top three in France qualify for the Champions League.

In Brittany on Saturday, Swedish striker Ola Toivonen gave Rennes the lead after 26 minutes, smartly chesting down a loose ball to score past Steve Mandanda in the Marseille goal.

Marseille were saved when Lucas Ocampos, the Argentine signed on loan from Monaco in the last moments of the transfer window, found the net in the 59th minute after coming on as a half-time substitute.
