Ibrahimovic has already scored four goals for PSG with doubles against Lille and Lorient and Friday's opponents Toulouse fear they will be the next victims when they visit the Parc des Princes.
"When you face one of the three best players in the world, in spite of anything you have prepared, if on that day he is the genius he can be, there is nothing you can do," Toulouse coach Alain Casanova was quoted as saying in Le Parisien on Wednesday.
"Unless you chain his feet and blindfold him, it's hard to stop him."
PSG are hoping Ibrahimovic's impressive form continues as they trail pacesetters and arch rivals Olympique Marseille, who have maximum points from four games, by six points.
"We are happy but let's not make too big a deal of this because everything is fragile," Marseille defender Rod Fanni told the club's website.
"One or two defeats and you are back to square one. Let's stay cool and we'll see."
"We are more solid, everyone is making more effort," said Fanni.
