Brazilian forward Neymar, who is nursing a foot injury, will also miss the game. "He is continuing his recovery programme with the physiologist and the doctor," Tuchel told a news conference on Saturday.
PSG will also be without German midfielder Julian Draxler, who has been suffering from a muscle injury. "Cavani and Draxler are not available," added Tuchel.
