Cagliari admit they've invited Roma to bid for midfielder Mauro Esposito.

"Talks with Roma for Esposito could take off in the very near future," noted Rossoblu sporting director Nicola Salerno. "Both clubs are busy with other transfer matters at this present moment, but there is time on our side."

Although the islanders are ready to release the midfielder, they still want to keep a 50 per cent stake in his contract.

"We haven't discussed figures with Roma, but we would prefer to sell him in a co-ownership deal," added Salerno. "Roma can offer the player the chance to increase his market value by allowing him to reach his highest levels again.

"Napoli, his own city, are keen on him even if Mauro would prefer a move to the capital given the stage they can offer him."
