You missed my point completely. So what they have a contract? The club no longer see them fulfilling its needs. It's not like Juventus is making them to play for free. Simply, we're no longer interested in their services. Such a situation happens in every football club, sports club or any business actually.
And it doesn't mean Juve failed as a club because they want to get rid of these players before their contracts end. What's more, if the reports are true, this bunch had plenty of decent offers yet they just won't fuck off. Take a look at Moise Kean for example. Opposed to those rats, he seems to still consider himself a football player and decided to go to Fiorentina.
