Ominously for the capital club's rivals, their latest big-money signing needed just three minutes to register his first goal for the club in Saturday's friendly clash with DC United.
Girard, though, believes that Ibrahimovic's signing is a positive thing for French football as a whole and is actually looking forward to coming up with a way of nullifying the forward.
"It's always good to have star players in our league, for the fans and the players," the 58-year-old told reporters at a press conference on Saturday.
"Particularly for the players it's going to be a good challenge for them to try to stop a top class player like Zlatan.
"It's not going to be easy. It's up to us to try to find the solutions and ingredients to make sure that he doesn't make a difference on his own.
"Paris Saint-Germain also have a lot of very good players so it's not just him. It's going to be interesting to see Ibrahimovic up close and it's going to be a good challenge for us trying to stop him."
PSG reportedly paid AC Milan €23 million for Ibrahimovic, who was top scorer in Serie A last season with 28 goals in 32 matches.
