Unbeaten Paris Saint Germain drew to within a single point of Ligue 1 leaders Marseille on Saturday with a come-from-behind 2-1 away win over Lorient.

Lorient stunned the champions with Raphael Guerreiro's tight shot opening the scoring on 42 minutes.

But Paris came back early in the second-half with goals from Edinson Cavani and substitute Jean-Christophe Bahebeck.

Marseille, who lost at Lyon last weekend, have 25 points ahead of their home game with Lens on Sunday and PSG have 24, as these two giants of French football get ready to go head-to-head in Paris next weekend.

Paris also maybe had one eye on their Champions League clash with APOEL of Cyprus in midweek, given the pedestrian nature of a sluggish first-half performance.

But they were given a rude awakening just before half-time.

Lorient came out of defence to launch a blistering break in their orange strip and yellow boots.

Andre Ayew took the ball into the box and fed midfielder Raphael Guerreiro, who stunned PSG goalkeeper Salvatore Sirigu with his sudden tight-angled shot to make it 1-0.

"We played badly all over the pitch in the first half. But you saw straight away the difference in the second half, and we got a goal straight away and went in for the win," the PSG 'keeper said.

And the difference was indeed eye-catching as Paris moved up a gear.

A defence splitting pass from Argentine playmaker Javier Pastore set up Cavani's equaliser just after the break, the Uruguayan nimbly hoisting the ball over the onrushing 'keeper before executing his traditional rifle-shot goal celebration.

It was his third goal in three starts.

Coach Laurent Blanc then made a double substitution bringing on Marco Veratti for the misfiring Yohan Cabaye and Jean-Christophe Bahebeck for a tired looking Ezequiel Lavezzi and it paid immediate dividends.

Veratti fed Bahebeck as he ran into space and his shot flew home from a tight angle to send a wave of joy through a relieved Paris side.

PSG can now look ahead to next Sunday with confidence.

"We are hoping for a great show next week and a great performance from both teams, we're all looking forward to it," said Sirigu.

In Friday's game Monaco drew 1-1 at home to Reims.

Later Saturday, Lille host St Etienne, Nantes welcome Rennes in the Brittany derby Sunday and Marseille will be keen to reopen a four-point gap on Paris when they host Lens in Sunday's late game.
