Roma and Napoli have reached an agreement over Kostas Manolas' move to Naples.
Italian reporter Fabrizio Romano has declared a swap deal has been struck, with Amadou Diawara moving to Roma in part exchange.
However, the players will be treated in two separate transfers.
Napoli will pay 34m for Manolas (plus 2m to the player as a signing-on bonus), giving the defender 4.5m per year.
For Roma, the sale of Manolas will give them some important capital gain, given their situation with UEFA and Financial Fair Play.
In return, they will sign Diawara for 18m plus 2m in bonuses, so strengthening their midfield.
