It is so nice to have some Italian core players in our squad. You can build on them and trust them, because mostly they will stay at one (top)club for a longer period. I have no doubt he will stay here for atleast another 5 years.
Look at Pellegrini (Roma), Immobile (Lazio), Insigne (Napoli), Bonucci and more who could've leaved to other foreign clubs but don't because they stay loyal to the place where they have a good time and make good memories. If Pellegrini was from a random other country he would have been Premier League bound for sure, same for Insigne, asked for him several times.
