Ten days for Gueye
After losing Neymar for month, Paris Saint-Germain will also have to do without lucky charm Idrissa 'Gana' Gueye, who also picked up a hamstring strain while on international duty.
Gueye, 30, who has proven crucial to coach Thomas Tuchel's plans since arriving in Paris from Everton in the summer, will therefore miss the Ligue 1 Conforama week 10 trip to Nice on Friday as well as the UEFA Champions League journey to face Club Bruges on Tuesday.
The news comes as a real blow for Tuchel, who has been beset with injury absences all season - most recently with Brazil star Neymar, who will be out of action for a month with his hamstring complaint, but also with star strikers Edinson Cavani, who is back in training, and Kylian Mbappé, still short of fitness.
Paris Saint-Germain have won and kept clean sheets in all eight matches that Gueye has featured in this season - in all competitions - and Tuchel will thus be hoping to have Gana fit again on schedule or beforehand as the Classique at home to arch-rivals Olympique de Marseille looms on 27 October.
