If Liverpool and Newcastle fail to draw a conclusion then I think that he might just endure the faith of actually leaving the club as a free agent or probably get in good terms with his and sign an extension contract because that's gonna be the best choice that's if the situation gets to that point anyway but for now let's sit and see how everything plays out for him, a move to Liverpool will definitely give Liverpool an upper hand in this year's title defense for sure so it's Liverpool that should hurry up and seal the deal.
Newcastle is just maintaining a stance that he won't leave and if he must leave then Liverpool must come up with that £150 million price tag or no deal. I don't think it's fair, since the player wants out and doesn't want to play for the team anymore they should respect his decision and reach out a deal with Liverpool so he can go. If he stays, the fans won't treat him well especially after all these saga around him and the club.
Newcastle United doesn't want Isak to leave the team if not they would have made it known to Liverpool so that if they want to make another bid they can meet up with the £150 million for the player, Isak is a good player but holding him back from moving to the team of his choice I'll likely affect his love for the Newcastle United team and it may as well affect his performance this season the current amount of €120 that Liverpool is willing to pay us enough for the player Newcastle United wants him at the club but Liverpool can get him as a free agent if his contract is no longer running right his current team. Fans has nothing against Isak it is the management that should be blamed for holding him back so if he decides to misbehave they shouldn't blame him either.
