As reported yesterday, last night’s Serie A game against Sassuolo could have been an important chance for Napoli 24 year old defender Federico Fernandez to show his value : despite the final result, the performance of the Argentina international has been quite disappointing, as well as the one of 32 year old Paolo Cannavaro, who also seemed intended to quit the azzurri during the last transfer window: even for this reason, Napoli keep on seeking a new defender: according to the Daily Express, the azzurri, as well as Arsenal and Manchesrter City, are keen again on Valencia 27 year old Adil Rami: the France internacional has been put out of the first team by the Spanish club’s executive board after a verbal fight with his coach Miroslav Djukic. Napoli are also seeking a high-skilled player for their offensive line, and, as reported by the British medias, are in competition with Juventus for Chelsea 25 year old Juan Mata. The Spain international is not the only player tracked by the bianconeri to reinforce their team's flanks: the Piedmontese club, in fact, are also seeking the heir of their right back Mauricio Isla, and, as highlighted by calciomercato.com, are thinking about FC Porto 22 year old Danilo Luiz Da Silva.
