Paris Saint-Germain missed the chance to move level on points with Marseille as they were beaten 4-2 by Bastia in Ligue 1 on Saturday.
Julian Palmieri s sensational volley from the edge of the penalty area – his first goal since November 2012 – put Bastia in front for the first time in the second half, before he added a second in the final minute as they climbed out of the bottom three.
Lucas Moura opened the scoring for PSG in the 10th minute, before Adrien Rabiot added a second 10 minutes later, with both taking advantage of slack Bastia defending to go two goals ahead.
Any hopes of a routine victory were dashed by two defensive lapses as Ryad Boudebouz converted a penalty after Gregory van der Wiel had handled, and Francois Modesto headed home from a corner.
Palmieri s sensational 25-yard strike completed an unlikely turnaround after 56 minutes, with Nicolas Douchez given no chance as the ball arrowed into the top corner.
Thiago Silva had PSG s best chance to get back into the game with 21 minutes remaining, but his effort struck the crossbar and after Palmieri extended Bastia s lead Laurent Blanc s side were left to reflect on a failure to capitalise on Marseille s 2-1 loss at Montpellier on Friday.
The result opened the door for Saint-Etienne to climb to third with a 2-1 win at Reims later in the day.
Yohan Mollo opened the scoring a minute before the break, and Romain Hamouma doubled the advantage three minutes after the players had re-emerged.
A 90th-minute Renaud Couhade own goal meant a tense finish for the visitors, but Antoine Conte s red card soon after helped to calm any nerves as Saint-Etienne held on.
At the other end of the table, Evian climbed out of the bottom three with a 1-1 draw at home to Rennes, lifting them above Lens 2-0 losers at Guingamp to 17th.
In the day s remaining fixtures, Lille triumphed 1-0 at home to basement club Caen, who are now without a win in 10 matches in all competitions, while Nice beat Lorient 3-1.
