This is correct and I understand his stance. No problem here. How PSG warned us, we will lose Skriniar for nothing in the summer, more than probably they also said him (or his agent) that a juicy bonus will wait for him, if he comes free.
2 things annoy me:
1. There were players in his situation who helped the club. Sadio Mane was one. He told Liverpool to sell him in his last year of his contract because he want lo leave. Bremer renew his contract with Torino even if he wanted to leave. If I am not wrong there was a similar rumour about SMS. They didn`t need to do this, but they try to be grateful to the clubs who nurtered them. Skriniar was nobody (do you remember Milano Skriniar?) before Inter. At the end of the day he gives no shit for Inter.
2. We need to let go this pussiness with the love between the player and the club. Skriniar, he bleeds nerazzurro, he shits nerazzurro and so on. Skriniar and nerazzurro, my ass!!! The contact between the club and the player is a transaction, not a relation. Simple as that! A player is just an employee, a asset on a spreasheet as @Universe
said. And nothing more. Even if the player is Di Marco, Bastoni, Barella and so on.
