Napoli president Aurelio de Laurentiis is ready to sell Kalidou Koulibaly to Manchester City.
TMW says negotiations over the 29 year-old's sale are now in the final stretch. A fee in the region of €70m is expected to be struck.
However, first Napoli wish to sign off on Allan's departure to Everton.
The midfielder is set to be sold by Napoli to the Toffees, despite claims in England of a loan arrangement being discussed.
Napoli are seeking €20-25m to sell.
