Arsenal finally gave up on getting the Newcastle United striker because their offer was rejected, or in other words, Newcastle didn't want to sell him. I think that the improvement in Isak's quality has attracted a lot of attention, but it's a shame that Arteta's target has failed.
For Eddie, of course he wants to keep Isak together because they have a big target this season to be able to compete again at the top of the standings.
So for the Gunners, of course they want to improve their front line because they need an attacker who can score lots of goals to bring them to victory in every match.
Also I wonder why Arsenal thought they may get him because it's obvious Newcastle are not like any other lower club that may be tempted by big money and I guessed Isak can only leave if he wants to which I doubt will be the case here since is love at the club.
I don't see any reason why Newcastle will sell Isak, a brilliant attack with great potentials and when he is on the field he contributes tirelessly to add impact on the match. Newcastle is a rich club and I don't think that they have plans of selling any of their main man because they also want to win the title and selling Isak will not be the best for them.
