Monaco's march towards Champions League qualification in Ligue 1 was slowed on Friday as they slumped to a 2-1 defeat at home to struggling Bordeaux at the Stade Louis II.

Goals in each half from Thomas Toure and Adam Ounas were enough for the away side before a Frederic Guilbert own goal gave Monaco a late consolation in the principality.

Monaco had looked certainties to finish second and secure automatic qualification for next season's Champions League thanks to an eight-game unbeaten run that included a 2-0 win away to champions Paris Saint-Germain in their last outing.

However, this first home league defeat since September means third-placed Nice can close to within two points if they can win at PSG on Saturday, while fourth-placed Lyon will also hope to put the pressure on when they visit Lorient on Sunday.

Bordeaux took the lead in stoppage time at the end of the first half when Fabinho inadvertently helped on a corner at the near post and the unmarked Toure lashed the ball into the roof of the net at the back post.

An almost identical goal allowed Bordeaux to double their lead before the hour mark as a corner came all the way to the back post where Ounas was this time unmarked and stabbed past goalkeeper Danijel Subasic.

Monaco had a chance to get one back in stoppage time when they were awarded a penalty for a Cedric Yambere foul on Guido Carrillo.

Vagner Love stepped up to take it but saw his effort saved, and although he converted the follow-up, the goal was disallowed, apparently for encroachment into the area by one of his team-mates.

The hosts did get one back, though, with Jerome Prior saving a Carrillo header only for the ball to rebound in off Guilbert.

Nevertheless, Bordeaux were not to be denied a first win in six games and a third victory against Monaco this season that allows Ulrich Rame's team to move nine points clear of the relegation zone.
