"It would be less complicated for Marco to play for Bayern one day than to join Madrid or Barcelona," he told Corriere dello Sport.
"Both Spanish sides have too many ties with Qatar to do something that could upset PSG."
However, the 23-year-old's representative insists his immediate future remains in the French capital, revealing it is only a matter of time before he will sign an extension, with his current deal due to expire in June 2019
"We have agreed terms over a new deal," he added.
"It is only a matter of putting it down on paper. Marco will stay with PSG for a long time, at least until 2020.
"This is already the fourth time he has signed a contract renewal since joining PSG.
"He now has to show again that he is worth his wages."
