"Neymar can leave PSG, if there is an offer that suits everyone," Leonardo told Le Parisien . "But to date, we do not know if anyone wants to buy him or at what price. All this is not done in a day, that's for sure.
"It's clear to everyone [that Neymar wants to leave], but in football, you say one thing today and tomorrow another. It's amazing but it's like that.
"We talked with his entourage too. Everyone knows everything. The position is clear for all participants. But one thing is concrete today: he still has three years of contract with us and since we have not received an offer, we cannot discuss anything."
He added: "PSG wants to rely on players who want to stay and build something big. We do not need players who would do a favour for the club by staying here."
Although Leonardo confirmed informal talks with Barcelona about a potential deal, he said no offer has been made for the 27-year-old.
"We have not received any offers. But we had, it's true, very superficial contacts [with Barcelona]. They said they wanted to buy but we were not sellers.
"[Bartomeu] is the one saying it, but we did not see that Barcelona was really in a buyer position."
