The source spoke on the condition of anonymity, in keeping with the club’s rules about official statements to the media.
The source also denied multiple reports in Spanish and British media that Messi’s father and agent, Jorge Messi, would be meeting with the club’s board this week to discuss his son’s future.
According to multiple reports, Messi believes he has a clause in his contract which allows him to leave Barcelona for free this summer.
Reportedly, the clause expired on Wednesday 10 June, but Messi and his representatives believe he still has the right to activate it now due to the season being extended because of the pandemic.
However, Barcelona insist that he must see out his contract, unless a release clause is paid, believed to be 700 million euros ($833 million).
“The club is not willing to enter into any negotiation for the player’s departure. The position of the club is that Messi has a valid contract until 30 June 2021 which the club would like to extend,” added the source.
