Monaco came close to a shock French Cup exit at the hands of third division Chambly but scraped through with a 5-4 away win after extra time in the last 32 on Wednesday.
Holders Paris St Germain avoided any such drama as they eased through with a 4-0 win at Stade Rennais courtesy of a Julian Draxler double.
In Chambly, goals from Guido Carrillo, Thomas Lemar and Kilian Mbappe put Monaco 3-0 ahead.
But the hosts fought back after the break as a Gregory Gendrey goal and a double by Anthony Soubervie, who netted the equaliser in stoppage time, levelled the tie.
Monaco defender Andrea Raggi was shown a straight red card for a dangerous tackle in the 89th minute, four minutes before Soubervie’s second goal.
Monaco kept their wits and went 5-3 up in extra time thanks to goals from Kevin NDoram and Kamik Glik.
Romain Padovani pulled one back for Chambly but despite being down to 10 men, Monaco held firm.
