Napoli star Ezequiel Lavezzi is on the brink of a move to PSG.
The reports were confident that a deal has been struck between the clubs for 27.5m plus performance-related bonuses and the profits from an August friendly match.
"Chatting to Lavezzi via text messages, I found out the news I hoped to the end I would not receive: the agreement with Paris Saint-Germain is done," fellow Argentine and ex-Napoli player Roberto Sosa told Sky Sport Italia.
"The rumours of the last few days were unfortunately true. It will be tough for Napoli to replace him."
