Atalanta now own Luca Cigarini outright after buying him from Napoli, but Michele Canini goes to a blind auction.
The Orobici announced they have reached an agreement with Napoli to buy creative midfielder Cigarini on a permanent basis, as he was previously co-owned between the clubs.
It is reported the cost of the 50 per cent was €2.7m.
Forward Giuseppe De Luca renewed his co-ownership status between Atalanta and Varese.
There is no agreement between Atalanta and Chievo for the future of defender Canini.
This means he’ll go to a blind auction: both clubs put bids in sealed envelopes and the highest figure wins the remaining 50 per cent of his contract.
