The Sweden international enjoyed a fruitful four year spell at the club, becoming the club’s highest goalscorer and claiming the ligue 1 four years in a row.
But since Ibrahimovic left the France giants for Manchester United, they’ve had a mixed start to the season, two wins and a loss in four matches.
Wenger recognises that PSG remain France’s powerhouse under new coach Unai Emery this term but believes they have lost a leader in the dressing room.
Speaking ahead of PSG’s Champions League encounter with Arsenal, Wenger said: “They will continue to be the dominant team in France but they lost more than a player with Ibrahimovic.
“He was the leader, the captain, a charismatic carrier of the ambition of the club and it’s always difficult to measure – when you lose a player of that stature – how big the damage is.
“At the moment they have also changed managers so they are trying to find their feet at the moment.”
