Marseille stretched their undefeated run at Rennes to seven games on Saturday but a laboured 1-1 draw meant they squandered the chance to go top in France.

Marcelo Bielsa's side are one point behind leaders Lyon who tackle champions and third-placed Paris Saint Germain in the weekend's standout fixture on Sunday.

In a depressing summary of Marseille's afternoon, they finished the game in Brittany with 10 men after Mario Lemina was red-carded for a foul on Ola Toivonen.

Swedish striker Toivonen was a thorn in Marseille's side all afternoon.

The 28-year-old gave Rennes the lead after 26 minutes, smartly chesting down a loose ball to score past Steve Mandanda in the visitors' 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.

The winger was handily placed to score from a corner taken by Dimitri Payet.
