Interista or not, Barella has done EVERYTHING you would expect from a loyal player to do. He rejected everyone to join Inter (Milan, Napoli, Roma, Chelsea). He never considered leaving the club even though he has been linked with the best clubs in the world. He agreed terms with the club over a new contract pretty fast and he tied himself to the club on a reasonable salary for his value till he's 29, so basically during his best years, giving Inter the upper hand in any negotiation. His love for the club and attachment to the jersey are undeniable. Inzaghi had even said Barella feels Inter jersey as part of his body. If Barella gets sold it will be 100% on the club's ownership and management. No one else.
