Christophe Galtier has warned any further delay in bringing new players to Paris Saint-Germain could scupper his team's chances of glory this season.
Head coach Galtier wants to usher away a number of fringe members of his squad and upgrade the overall quality ahead of a Champions League mission.
Alongside the defence of their Ligue 1 title, the priority for PSG is to land European glory this season, and Galtier has players in mind who he feels can help the capital club achieve their goals.
"Two weeks ago, I said we were expecting three new players," Galtier said on Friday.
The likes of Vitinha, Hugo Ekitike and Renato Sanches have already arrived during the transfer window, while Arnaud Kalimuendo, Thilo Kehrer, Angel Di Maria and Georginio Wijnaldum have left the Parc des Princes.
However, Galtier sees room for further strengthening of his squad, and despite saying he has seen promising signs of progress, the September 1 deadline is looming large. He and football advisor Luis Campos are in close contact, looking for solutions.
Inter defender Milan Skriniar has been strongly linked with a switch to PSG in recent weeks.
Ahead of Sunday's trip to Lille in Ligue 1, Galtier said: "We have identified players who could really help us out. Then there is the reality of the transfer market and both the financial and commercial aspect.
"We have lots of players under contract. That is why the club is looking to the ability to loan players out to different clubs, to reduce the number of contracts at the club.
"That is the first thing. With Luis Campos, we talk every few days about the squad, but there is a time delay between the financial, commercial and sporting sides."
Although PSG have made a rollicking start in Ligue 1, scoring 10 goals across two games so far, Galtier knows they have areas where improvements can be made.
"We are in a rush," he said. "In a week's time, we will be playing every three or four days. The schedule will be very busy. It is not easy to integrate a player when you're playing every three or four days.
"Delaying their arrival could affect our sporting plans. We don't want the squad to be the biggest possible, but with as much quality as possible. We don't want the quality to suffer."
