Here we go again with the endless and pointless debate about Gagliardini and Vecino. They're both shit and they both have no business playing for Inter.
Vecino can only make forward runs to opponent box. That's it. He is a defensive liability and he can only be useful against midtable teams or as a scoring threat late in the games when we desperately need a goal. And even his goal scoring ability is overhyped because of his important clutch goals in the past.

Another thing we need to add about Vecino is he has been an injury prone in the last two years so even his availability would be in question in case he stayed. He also earns 2.5m net per season.
As for Gagliardini, unless we face teams from the beautiful city of Genoa, he offers absolutely nothing. No defensive security, no physicality, no forward runs, no great passing, no vision, no goals, no assists. Nothing at all. He's just there and he's usually available.
A normal team would try to offload Vecino this summer and either offload Gagliardini next summer or keep him as a 7th midfielder, due to his low wages, and use him either only against the bottom of the table or in case of an injury crisis. But we aren't a normal team so i wouldn't be surprised if both of them ended up staying and either, or even both, of them had an important role in the upcoming season.
