Among those players going to a blind auction are Emiliano Viviano and Gaetano D'Agostino, but Inter lose Marco Andreolli.
The deadline for the co-ownership deals has now passed and some clubs have not been able to reach an agreement on whether to renew or buy a player outright.
In tomorrow's blind auction, each club writes a figure in a sealed envelope and the highest bid wins the player.
Those who have gone to the auction are D'Agostino (Fiorentina-Udinese), Albin Ekdal (Bologna-Juventus), Riccardo Meggiorini (Bologna-Genoa) and Gianni Munari (Lecce-Palermo).
The biggest name still in the balance is Italy number two goalkeeper Viviano, who is co-owned between Bologna and Inter.
The two clubs have been unable to reach an agreement, so his fate will be decided by a blind auction.
The same goes for D'Agostino, who a year ago was the subject of a bidding war between Juventus and Real Madrid.
Now he finds himself unsure whether Udinese or Fiorentina want to buy him outright.
Some decisions were reached right at the deadline, as Inter have sold their half of Italy Under-21 international Andreolli to Chievo.
Roma snapped up goalkeeper Gianluca Curci from Sampdoria, while Parma took Daniele Galloppa from Siena.
Bari bought Abdel Ghezzal from Siena, while Roma completed ownership of Sampdoria's Stefano Guberti.
Sampdoria secured the other 50 per cent of Daniele Mannini's contract from Napoli.
