Bordeaux go second
Bordeaux came back from three goals down to beat Monaco 4-3 and go second behind Lyon after fellow title pursuers Paris Saint Germain and Marseille let valuable points slip on Sunday.
PSG were held 2-2 by Valenciennes while down at the Velodrome stadium, Nancy meted out a 3-0 drubbing to Marseille.
In Sunday's late game Bordeaux, who could have gone clear second, were trailing 3-0 and looking down and out after Juan Pablo Pino's 12th minute opener and a double by Alexandre Licata either side of the break.
Marouane Chamakh pulled one back in the 52nd minute with Alou Diarra reducing the deficit further a quarter of an hour later, but still the visitors were facing defeat.
With two minutes of regulation time remaining, Chamakh got his double with Argentinian Fernando Cavanaghi the hero of the hour bagging the decider in the closing seconds.
Marseille were undone by a Youssouf Hadji first half double with Issiar Dia adding further misery in the 56th minute for mid-table Nancy's sixth win of the campaign.
Up in the French capital PSG were unable to follow up their heroics on Thursday when they thumped Dutch side FC Twente 4-0 to book their place in the UEFA Cup last 32.
Paul Le Guen's in-form team were seeking their sixth success in seven outings but could not overcome a determined Valenciennes side who came back twice to take a share of the spoils.
