Panucci has been impressed by the Frenchman this season.
He told MilanNews.it: : "When he arrived at Milan, not many knew him, but he soon proved to be a flexible player, strong on the right as well as in the middle. Last year he played an extraordinary championship, certainly contributing to the victory of the Scudetto.
"With the victory, the awareness of having imposed himself individually in a prestigious context came, which allowed him to continue growing faster and faster.
"It is not easy to understand where he can go, but already at this moment he is a very important player for a team like Milan."
