It doesn't but if he wants to leave because he doesn't get on with <random> then he is completely free to. I don't see the problem. It's not about saving face because some fan from Taiwan might laugh at you on Twitter, it's about the good of the team and getting worthwhile financial compensation. Unfortunately if a player becomes a problem they end up getting you over a barrel and the interested team can aim lower.
Sure we can do a PSG with Verratti, as I keep hearing. I wouldn't even want a Bonucci at Juve that wasn't focused on doing his best for us because he is in a sulk, he turns into an absolutely liability when he's not focused. So you end up with a shit season and decreased value, it's a downward spiral.
