It's unfortunate Isak decides to put his career at stake knowing he's still under contract. I respect Newcastle for standing firm on this issue by the way.
I totally stand with Newcastle, players must understand that contracts work both ways, they are not just a piece of paper. There is no respect in football, they think they can do whatever they want.
At the same time if it's true that Liverpool offered 140 mln euros for a player like Isak in my opinion they should accept, he's not worth that money.
