Former Zenit St Petersburg chief Oreste Cinquini is unsure about Napoli's move for Khvicha Kvaratskhelia.

It's emerged the Rubin Kazan winger is set to join Napoli this summer to replace Lorenzo Insigne, who is leaving for Toronto FC at the end of the season.

Cinquini told TMW: "He is a good player, who showed excellent things especially in his first season at Rubin, while in the second season he struggled a bit. I repeat, he is an interesting player but he needs to be tested in our league.

"Well, physically he is the double of Insigne. In any case, he is a right foot who enters the field just like Insigne does. Let's see him in Italy, here there is a different quality compared to the Russian championship on a technical-tactical level."
