Mauro Icardi scored a hat-trick as Paris Saint-Germain demolished a depleted Saint-Etienne 6-1 on Wednesday to power into the semi-finals of the French League Cup.

Icardi struck the opening goal inside two minutes at the Parc des Princes before teenage Saint-Etienne defender Wesley Fofana was dismissed for a second booking on the half-hour.

PSG ruthlessly capitalised on their man advantage as coach Thomas Tuchel elected to field all four members of his fearsome attacking quartet -- Icardi, Neymar, Kylian Mbappe and Angel Di Maria -- against a side decimated by injury and illness.

Neymar doubled the lead with a nonchalant chipped finish over goalkeeper Jessy Moulin, who scored a comical own goal on the stroke of half-time.

Di Maria’s low cross was hacked by Timothee Kolodziejczak into the legs of team-mate Loic Perrin, the ball rolling back off the post before hitting Moulin and trickling over the line.

The hosts bagged a fourth when Mbappe rounded Moulin and cut back for Icardi to add to his tally, and he completed his hat-trick when the former raced clear before selflessly presenting the Argentine with a tap-in.

The pair reversed roles for the sixth goal, Icardi controlling superbly and sliding across goal for a lunging Mbappe to turn home from close range.

Former PSG midfielder Yohan Cabaye hit a consolation goal for Saint-Etienne when he headed in the rebound after his second-half penalty was saved by Sergio Rico.

PSG have now scored at least four goals in their past six matches. The record eight-time champions will discover their semi-final opponents when the draw is made on Thursday.

Lyon battled into the last four with a 3-1 victory at home to Brest.
