An injury-time goal by substitute Nicolas Maurice-Belay gave Bordeaux a 2-1 home victory against relegation-threatened Lens in Ligue 1 on Sunday.

Despite the win, Bordeaux have their work cut out to finish in the top four -- the only places guaranteeing European football next season -- as they are now in sixth place on 51 points, three behind fourth-placed Monaco, who have a game in hand.

When Mariano broke the deadlock going into the last 10 minutes, it looked like Lens would once again rue missed chances.

But Pablo Chavarria fired Lens' hopes of Ligue 1 survival with a fine finish just three minutes from time.

Maurice-Belay, however, came off the bench to grab the winner in injury time after pouncing on an Ahmed Kantari mistake.

The defeat leaves Lens bottom, nine points from safety and one point behind Metz, who beat Toulouse 3-2 on Saturday to record their first victory since November thanks to a Modibo Maiga hat-trick.

On Saturday, Lyon reclaimed top spot in Ligue 1 with a 3-1 win at 10-man Guingamp, putting the pressure on fellow challengers Paris Saint-Germain and Marseille before they meet on Sunday.

Lyon, who won the last of their seven Ligue 1 titles in 2008, now have 61 points from 31 games, two ahead of champions Paris, with Marseille another two points back in third.

The Parisians can strike a major blow in the title race by continuing their impressive recent record at the Stade Velodrome.

Laurent Blanc's side have dominated the fixture known as 'Le Classique' in recent years, with their 2-0 win at the Parc des Princes in November their sixth in a row against Marseille.
