PSG are reportedly concerned that Manchester United would be prioritised should a Qatari bid for the club be successful.
A Qatar-based consortium has launched a bid for the Old Trafford side as the Glazers look to sell the club.
The Glazers revealed in November that they were willing to listen to offers for either a stake in the Premier League giants or an outright purchase.
A number of parties have expressed an interest in buying United, which could be purchased for a world-record price for a sports franchise at £4.5billion, or more.
The Daily Mail reported that a bid from the consortium would not be blocked by UEFA, which would bring a major cash boost to United.
The block may have happened due to the ban over one owner controlling more than one team in their competitions, such as the Champions League.
The report says that the bid has come from a separate entity to Qatar Sports Investments, which owns the Ligue 1 giants.
PSG was taken over by QSI in 2011 and have since gone on to become one of the heavyweights in European football.
The French side have won eight of the last ten league titles and are consistently reaching the latter stages of the Champions League.
Qatar authorities has insisted that the bid for the Premier League side will not affect PSG and that the French side will continue to receive funding.

Reports, however, do claim that there will likely be an impact on PSG.
One reason for this would be due to private investors for United wanting Qatar Investment Authority, which is the sovereign wealth fund of the country.
This reports to Emir Tamim bin Hamad al-Thani and it will be up to him to decide on the investment into United.
The Daily Mail report has suggested that that would cause concern over the fact that Qatari investors would own two of the most famous clubs in the world and where their money would be going.
Another reason for worry is that the bid comes during PSG’s concerning form, as they are not as dominant in the domestic league.
The club are also struggling to win the Champions League, despite heavy investment into the playing squad.
Therefore, United could be prioritised should they become more successful.
One source told L’Equipe: “If Qatar buys Manchester United, there is a chance that it will be less generous with PSG and that it will make it a Ligue 1 club and no longer a team cut out to win the Champions League.”
