Montpellier midfielder Ryad Boudebouz says PSG are weaker without Zlatan Ibrahimovic.
The Swede left PSG for Manchester United last summer.
Boudebouz told Canal Plus: "The departure of Ibrahimovic has weakened PSG. When he was there, it was much more impressive.
"Today, Paris is in a period of doubt. And teams have less fear and that does not please them ... And now, we must shake up this team of Paris.
"They are talented players, if you let them play, they'll score three or four."
