Expanding the rumor, where do you think Isak would go if Newcastle successfully acquires Jackson from Chelsea? Isak's contribution to Newcastle has been significant during his time at the club, and if Isak's departure were to materialize, I'd prefer him to be at a club much stronger than Newcastle. A player of Isak's age, there are certainly still several teams interested in him if Newcastle gives him the green light to make things happen.
Jackson to Newcastle is a mere rumor and I don't believe that, it would be so disappointing to Newcastle fans seeing their club move from one of the best 9 in the league to Jackson, anyways if the rumors are true then it means Isak would push to move over to Liverpool, I learnt that they're already planning on selling Nunez, that plus the funds they'll get from Diaz's deal would give them enough advantage to sign Isak, but Isak too has a role to play to make the deal happen as swift as possible, he needs to show interest of leaving Newcastle and also declare an interest of switching to Liverpool, so Newcastle would quickly give Liverpool the green light.
