Paris Saint-Germain could struggle to hold on to Marco Verratti this summer following comments made by his agent Donato di Campli.
The midfielder's representative has suggested that the Parisian club is holding him back and that he may have to move elsewhere to taste glory.
"It's a complicated situation," Di Campli told La Gazzetta dello Sport.
"He has a contract until 2021 and he wants to have success, but PSG, as they are right now, cannot do that."
The agent was adamant that the doubts had nothing to do with the 24-year-old's salary and that all that mattered was finding the right platform to win.
"He needs to consider whether he wants to earn a lot and be a champion or if he wants to earn a lot and not be one," the Italian newspaper was told.
"It's not a matter of money because he'll earn a lot wherever he goes.
"If he does leave then he'll join a big European club."
With Barcelona having been linked with the player for several years, a move to the Camp Nou could be attractive for both parties.
