Napoli will probably go back on to the transfer market after defender Gianluca Grava was ruled out for the season.
Grava collapsed in agony during Saturday's 0-0 draw against Fiorentina at the Stadio San Paolo.
It became immediately apparent that it was a serious setback and reports do suggest he has torn knee ligaments.
If the tests confirm the diagnosis, then Grava will be out for around five to six months.
“We will miss him, both on the field and in the locker room,” said captain Paolo Cannavaro (pictured).
“The injury looks serious, we know it'll be tough for Gianluca and I believe the club will turn to the transfer market.”
Napoli had already been linked with Torino and Italy Under-21 international Angelo Ogbonna.
Toro want €10m for the player, whereas the Partenopei have so far offered no more than €7m.
It is also likely that Napoli will now opt to keep Fabiano Santacroce rather than loan him out to Lecce.
