The coach believes that the Ligue 1 champions are being damaged in the transfer market by the regulations after they agreed a deal to sign Serge Aurier on an initial loan
Uefa imposed sanctions on the French side earlier in 2013 after finding them guilty of a breach of FFP regulations, meaning that their spending powers have been curtailed for the current transfer window.
That did not stop PSG splashing out €50 million (£40m) on David Luiz, however, while Real Madrid's Angel Di Maria has also been linked with a move to the French champions.

"We do not do what we want, you know as well as me. If you are told that this is the formula, it is there for a reason," he declared to the media.
"Financial fair play will bother us - we have already felt the discomfort but it did not prevent us from recruiting two key players, Serge Aurier and David Luiz. But it is true that we cannot do what we want, we knew that."
Aurier was signed on an initial loan deal from Toulouse, with PSG retaining an option to buy the Ivory Coast international permanently in future, and Blanc is delighted to have acquired the 21-year-old in an arrangement which will do little to incur further problems with FFP.
"It gives us pleasure, we have the opportunity to bring him to Paris so we are very happy to have him with us," the coach enthused. "He is a young boy with a great potential and good margin for progression.
"I hope that he will grow and become an important element for the future of the club."
