Napoli president Aurelio de Laurentiis has told Manchester United and Manchester City they can buy Kalidou Koulibaly - for the right price.

De Laurentiis says the defender will only leave for his set price.

He told Corriere dello Sport: "If City or United or PSG with €100m (£90m) showed up, I would think about it and it is probable that they would leave, always if their will was to leave.

"I don't even consider an offer of €60m (£55m). I am solid, if I wanted to win the Scudetto at any cost today I would find myself with three, four hundred million debts.

"I look around and see companies at 500, 600 million, less a billion. I don't owe anyone a s***."
