International reports claimed on Monday that Paris St-Germain (PSG) are unsure that Brazil forward Neymar will not sign a contract extension with the French club.
Marca newspaper reported that Neymar's continuation at Paris Saint-Germain is far from guaranteed, despite the club being convinced that he would renew not so long ago.
"The Brazilian has been linked with a return to Barcelona, though there are doubts about the Catalans' ability to pay for his move and salary," it said.
"We have to be calm about everything," he said to El Chiringuito on Sunday, when he was in Barcelona to watch PSG's women's team lose to Barcelona in their Champions League semi-final.
Leonardo refused to give any more away, despite being asked specifically about Neymar and Kylian Mbappe.
"Today I've come here to watch the women's team," he said. "Unfortunately we've lost."
