Cagliari sports chief Nicola Salerno has warned a proposed move to Napoli for midfielder Mauro Esposito could fall through.

"As reported in the press, it is not wrong, it is true that there is a danger that the negotiations will fail," said Salerno. "The situation should become clear in the coming hours, at most within a couple of days."

Genoa chief Giambattista Pastorello, meanwhile, has confirmed the stalled negotiations could let them in to make a counter offer for Esposito.
