It's very interesting to see Isaak has declared his interest to play for Liverpool. I think he will fit to the club, and it's good for Liverpool to sell Nunez, then add more money to sign him from Newcastle.
It will better if he can forces his club to decrease his release clause, then he can move to the Liverpool asap.
Liverpool combined with him is gonna be a great combination. I hope that is gonna happen soon.
If he had shown interest in moving to Liverpool, the chances of him moving would have increased. Darwin Núñez has not lived up to expectations and the future of Muhammad Salah is not clear, it will be safe to sign Alexander Isak to keep their attack sharp and dangerous. Selling Darwin will pave the way for Swedish professional footballers since it might make them free from the infringement of the financial fair play rules. Another consideration is whether Newcastle will be willing to give out their main striker.
