Edinson Cavani scores the winner as Paris Saint-Germain win the Coupe de France

Paris Saint-Germain have secured domestic treble with a narrow win over Auxerre in the final of the Coupe de France.

Auxerre dominated in the opening 15 minutes, but they failed to seriously test Nicolas Douchez in the PSG goal.

However, they almost fell behind as Edinson Cavani went close for the Ligue 1 champions when he latched onto the end of a Lucas Moura cross, only to direct his header a few inches over the crossbar.

PSG dominated from then on as Zlatan Ibrahimovic went close to breaking the deadlock twice in five minutes, but Auxerre goalkeeper Donovan Leon made a couple of point-blank saves to keep the scores level.

Leon could not do anything about Thiago Motta's effort a few minutes after, as the Italian smashed a shot from the edge of the box against the post.

PSG continued to hold the upper hand after the break as Cavani forced Leon into another reflex save from close range.

However, Leon could not deny the striker for a third time as he powered in Gregory van der Wiel's cross from a few yards out.

Auxerre pushed forward in search of an equaliser and almost found one as Diarra found some space in the box, but his low effort was comfortably saved by Douchez as PSG held on to win.
