Kylian Mbappe was sent off as Paris Saint-Germain booked their place in the Coupe de la Ligue final with a 3-2 win over Rennes on Tuesday.
The 19-year-old, who returned to the starting line-up after missing two games with a back injury, was shown a straight red card for a poor challenge on Ismalia Sarr in the second half at Roazhon Park.
The dismissal did not prove fatal to PSG's hopes of keeping alive their quadruple chase, though, with Thomas Meunier, Marquinhos and Giovani Lo Celso having put the game beyond Rennes' reach inside the hour, although they were forced to hold on in the dying minutes.
PSG came into the fixture having not lost a Coupe de la Ligue match since a penalty shootout defeat to Saint-Etienne in November 2012, but they struggled to find their feet until Meunier blasted in a volley 24 minutes in.
Marquinhos made it 2-0 from close range eight minutes after the restart and Lo Celso's first goal for the club soon followed, the midfielder scoring just 13 minutes after coming on to replace Javier Pastore.
Mbappe earned his first red card of his club career with a crude lunge 63 minutes in, with referee Mikael Lesage showing a red card after a VAR referral, and Diafra Sakho's debut goal gave the home side some hope.
Sanjin Prcic fired home a second in injury time but PSG survived to reach yet another domestic final.
