Despite Isak’s strong interest in a move to Liverpool and his desire which he has shown by protesting and going on strike against his parent club Newcastle United still need to reach an agreement with Liverpool before a deal can happen so they have to wait for Newcastle. I think Newcastle United are seeking a replacement before agreeing to a deal that will see Isak leave the club.
How long before the transfer window shuts down? No news yet on Newcastle and Liverpool coming to a positive agreement, any price bid for the striker is appropriate, this is the most anticipated transfer news i expect to get concluded very soon. If Liverpool don't come to agreement with Newcastle, the season won't be fair for Isak as he already isolated himself from the club and may not be giving the chance to play alongside the team, as his movement was a protest to join another club.
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.
