Edinson Cavani has agreed a deal with Chelsea, after Napoli accepted a €58 million (£49 million, $76 million) fee.
Radio Marte, Napoli's official radio station, confirmed the deal, citing a "very reliable source", with Cavani set to sign with Chelsea on a deal worth €8.5 million per season (£7.2 million, $11 million).
"We have received news in the office from a very reliable source that Napoli have sealed a deal with Chelsea for Cavani's sale," Radio Marte said.
"Rafa Benitez also gave the all-clear, but before making the move official Napoli want to secure the striker who will replace Il Matador.
"Aurelio De Laurentiis' club will pick up around €58 million, a slight discount on the buy-out clause, which is the same situation as Ezequiel Lavezzi to PSG last year. The player will earn €8.5m per season plus image rights."
If the reports do turn out to be, it will be a big coup for Chelsea and Jose Mourinho, making a big statement ahead of the new season, with several clubs expected to fight for top place in the English Premier League.
Cavani has been pursued by Manchester City and Real Madrid as well, but now it seems like Chelsea have won the battle for the coveted Uruguayan's signature.
Meanwhile, Tottenham manager Andre Villas-Boas, who spent quite a bit of time as Mourinho's assistant, believes the Portuguese's return to the Premier League will mean all eyes will be on Chelsea come next season.
"It won't be possible to take your eyes away from Mourinho," former Chelsea manager Villas-Boas told O Jogo. "One of his characteristics -- and I don't say it in a negative way -- is to deviate attentions, positive and negative, in such a way that the team is only worried about winning."
Villas-Boas admitted he has made some mistakes during his short and unsuccessful spell with Chelsea but was now much the wiser, having had a good first season with Spurs.
"The Premier League is guided by this dynamic: ball lost, ball recovered, ball lost again," he added. "That makes matches unpredictable. Teams must be objective and behave like that, because that's what excites fans.
"The aesthetics of the game come second to unpredictability, which is much more exciting than the predictability associated with possession football.
"I should have had respected that culture from the start. I thought it was possible to establish a different game pattern in a country with a radically different culture. I respect it now.
"I have become more versatile after the Chelsea experience."
