The race for Edinson Cavani's signature may not be over after Napoli chairman Aurelio de Laurentiis revealed the £53 million release clause in the striker's contract expires on Auagust 10.
Cavani has been the subject of intense interest from some of Europe's biggest clubs this summer, and has hinted he is looking for a move away from Napoli.
However his suitors have so far been unwilling to offer the £53 million required to activate his release clause.
De Laurentiis confirmed last week that Manchester City were to go near that figure in order to land the Uruguayan.
"Manchester City do not have money to pay for Cavani, because they say, 'We won't pay that [£53m]," he said at Rafa Benitez's unveiling as manager.
Chelsea have reportedly had a string of bids under that figure rejected, and are said to have switched their attention elsewhere to Borussia Dortmund's Robert Lewandowski.
However De Laurentiis offered the likes of Chelsea, Manchester City and Real Madrid a glimmer of hope by revealing that the sky-high release clause will expire before the end of the summer transfer window.
"I don't think Cavani will leave on August 10th, when his buyout clause expires. I'm confident in him, because I consider him a real man. He won't make a joke of me," said De Laurentiis.
'Should Cavani want to leave, he will decide it after a long period of reflection. But by July 20th we will probably know everything about his future."
Cavani dropped another hint that he was willing to leave Napoli, saying he is 'flattered' to be linked with some of Europe's biggest clubs.
"I'm flattered by the interest of certain teams. Who would ever say no to Real Madrid or Chelsea?
"We'll see what happens. There are many rumors but nothing concrete."
