Playing on a rain-soaked pitch, Monaco twice squandered a one-goal lead and looked destined for a fifth draw out of six matches.

But Givet reprieved his team mates seconds before injury time when he nodded home from a cross by Mexican defender Rafael Marquez.

The decisive pass allowed Marquez to make amends after scoring Ajaccio's first equaliser when he beat his own goalkeeper Flavio Roma in the 79th minute before he was responsible for a penalty awarded to Ajaccio three minutes from the final whistle.

Congo's Shabani Nonda had given Monaco a deserved lead when he deflected the ball off a Corsican defender to open the scoring in the 63rd minute, bringing his goal tally this season to eight.

Souleymane Camara then put Monaco in front with another header in the 84th minute before the Corsicans levelled three minutes later from a penalty taken by Bruno Rodriguez for Marquez' foul.
