Paris St-Germain sealed another domestic treble, but were made to work hard by third division Les Herbiers for victory in the French Cup final.

The underdogs started – and ended – strongly, but the French champions were ultimately too good for them.

Paris St-Germain had hit the post three times before Giovani lo Celso curled home from 25 yards.

PSG had a goal ruled out by the video assistant referee but Edinson Cavani scored a penalty to seal the win.
