The Azzurri had been hot on the trail of the 24-year-old for quite a while, but they seem to have finally succeeded in their quest to lure him to Stadio Olimpico.
La Gazzetta dello Sport reports that Napoli have had a €13 million bid accepted by Lyon, while they also struck personal terms with the midfielder.
As a result, Gonalons is set to sign a four-year deal with the club worth €1.5 million per campaign plus bonuses.
Napoli president Aurelio De Laurentiis is hoping to officially announce the deal ahead of Monday’s clash against Sampdoria, where the Azzurri are 4/11 to return to winning ways.
Maxime Gonalons has spent his entire career up to date at Stade Gerland and was handed a captain’s armband at the start of last season.
