Paris (AFP) - Maxime Lucu kicked a last-minute penalty as Bordeaux-Begles defeated French Top 14 leaders Montpellier 23-22 on Sunday.
The result allowed second-placed Bordeaux to cut the gap to just two points.
Lucu finished the game with a personal haul of 18 points with hooker Maxime Lamothe scoring Bordeaux's only try after seven minutes.
It was a welcome win for a Bordeaux side which had suffered eight defeats in nine matches.
For Montpellier, who have a European Champions Cup quarter-final date with French rivals La Rochelle in two weeks' time, it was a first home loss since a 22-20 defeat to Clermont in mid-October.
However, they came close to victory in the closing stages of Sunday's game as Bordeaux's discipline deserted them.
A yellow card for back-row forward Mahamadou Diaby in the 64th minute allowed South African star fly-half Handre Pollard to kick three penalties.
Lock forward Florian Verhaeghe then scored a converted try in the 76th minute as Montpellier edged 22-20 ahead.
But that was the cue for Lucu to boot his nerveless last-gasp penalty to secure the win for Bordeaux.
