Napoli president Aurelio De Laurentiis says Edinson Cavani will be allowed to leave the Partenopei this summer - but only if a club matches his £60 million buy-out clause.
Cavani has been routinely linked with Premier League duo Chelsea and Manchester City this season, with Paris Saint-Germain also reported to be interested in the 26-year-old.
It was previously thought that the Uruguay international had a release fee much less than the figure quoted by the Naples club, but it now seems only an extraordinary bid will be enough to prize him away.
"We included a very high buy-out clause in his contract because we want him to stay at Napoli," De Laurentiis told reporters.
"The clause exists, though, and if some nutter is willing to pay €70m [£60m] for him, which would mean a net fee of €63m [£54m] for Napoli, we are ready to listen to the offer.
"However, let it be clear that the final decision lies with Edinson.
"He knows that he's respected here and that the people love him. Not just for his goals, but also because he's a serious and polite person."
