Paris Saint-Germain defender Presnel Kimpembe apologized to the team’s fans over a megaphone after the 3-1 Ligue 1 defeat by Monaco.
PSG, who were without Kylian Mbappe, Lionel Messi and Marco Verratti, lost twice in four days.
On Tuesday, PSG hosts Bayern Munich in the 1/8 finals of the Champions League.
Top scorer Mbappe has already been ruled out of the first leg at the Parc des Princes with a thigh injury, and PSG coach Christophe Gaultier is hopeful Messi will recover in time from the hamstring problem that kept him out of Monaco.
PSG’s young side were 2-0 down after 18 minutes and although 16-year-old Warren Zaire-Emery had one shot, Ben Yedder scored his 19th goal of the season to secure victory in first-half added time.
France defender Kimpembe was replaced as Mbappe’s vice-captain last month.
Reigning champions PSG remain top of the table, five points ahead of Marseille, with Monaco two behind.
PSG have lost three of their seven league matches in 2023, with their latest defeat coming after they were knocked out of the French Cup by Marseille on Wednesday.
