Napoli president Aurelio de Laurentiis admits Allan is on his way to Everton.
The Brazil midfielder is now waiting for the two clubs to shake hands on his transfer fee.
De Laurentiis told Radio Kiss Kiss Napoli: "We have reached the final salutes. He will go to Everton."
Everton made a breakthrough in negotiations concerning the midfielder with the Serie A club over the weekend and now a deal is close to being agreed.
Carlo Ancelotti has highlighted central midfield as one of his side's top priorities to improve over an important summer transfer window, and is keen on linking up with the 29-year-old once more.
