PSG have informed Barcelona of the price for Adrien Rabiot.
Barca directors Pep Segura and Eric Abidal have been in Paris this week to discuss terms with PSG over a deal for Rabiot.
Le Parisien says PSG have told Barca they will sell the midfielder for a fee of €40m.
Despite the arrival of Arthur Melo from Gremio, Barca are also keen to push through a deal for Rabiot.
For his part, Rabiot is keen on joining Barca, with his mother Veronique having spoken with Abidal last week about setting up a transfer.
