De Laurentiis, president of Napoli, is tired of the rumors about Milik. Teams like Atletico and Juventus have been linked as possible destinations day after day.
'Mundo Deportivo' claims that the Italian club has made a proposal to extend Milik's contract, which expires in 2021.
This means that, if Milik does not want to extend it, Napoli would be facing its last chance to cash in on its summer market sale. Next summer he'd go totally free... and they want to avoid that at all costs.
That is why Napoli would have given Milik an ultimatum: he must decide what to do with his future within 20 days at the latest.
If he does not want to accept Napoli's proposal, they will sell him, but they do not intend to give him away. 50 million euros is the price they have set for the defendant footballer.
