But Grassani told Radio Kiss Kiss Napoli: "We're not there yet, you have to be patient.
“Not everything is done yet because [President] Aurelio De Laurentiis takes care of the smallest details and then dictates the line to me.
“He doesn't want to leave anything to chance in the future. When a Coach changes teams he tends to bring along two or three loyal lieutenants, De Laurentiis doesn't want that to happen so we're taking care of those details.
“De Laurentiis wants to close this window, after Jorginho goes to Chelsea then the route from Naples to London will be closed, for any player.
“Today or tomorrow Sarri could sign, it's close and is about to happen.
