Coutinho has been linked with a move away from the Nou Camp, following an indifferent campaign with the LaLiga champions.
The Brazilian playmaker, who joined from Liverpool in January 2018, was the target of boos from fans towards the end of the season.
Paris Saint-Germain, Chelsea and even Liverpool have been touted as his destination this transfer window.
But his agent has claimed Barca want to keep the 27-year-old.
“I talked a few days ago with Pep Segura at Barcelona.
“He told me that the club does not want to sell Coutinho this summer, no matter what. And then, we have not had any contact with PSG” Joorabchian told RMC Sport.
