The Newcastle striker will be in the spotlight of many teams. The calls for Arsenal to sign a new striker are growing, and the 25-year-old seems like the perfect choice.
Isak's move to the Emirates has been a hot-tempered move without any real approach being given. But there are some signs that the "Gunners" are planning for this deal.
The signing of Mikel Merino last summer means that, along with Martin Odegaard, Arsenal currently have two of the three starting midfielders in the Real Sociedad squad from the 2019-2020 season. And who is the central striker in that squad? Isak.
Real Sociedad's outgoing sporting director, Roberto Olabe - who signed Isak for La Liga club in the same season - is also being linked with a possible replacement for Edu at Arsenal.
However, the main reason Arsenal want Isak is because he is one of the most complete strikers in Europe at the moment. Mikel Arteta's side seem to be lacking such a 'number 9' model to conquer the title.
Since the last week of October, only Mohamed Salah has scored more goals than Isak in all competitions, counting in the top 5 European national championships. One of those goals from the Swedish striker was the decisive goal against Arsenal in early November.
Along with three other assists in that time, Isak is proving why he is considered the most complete striker in the league. The 25-year-old's sudden increase in goals and assists came surprisingly. Newcastle's slow start to the season and Isak's toe injury have left him with just one goal in his first eight league games.
But as soon as coach Eddie Howe was able to find balance in key areas on the pitch, it created a structure for Isak to thrive.
"New Newcastle are also creating chances for Isak. Not that he did it himself, the team is playing really well not only for Isak but also for the other players. We are seeing goals from different aspects of the team.
When you run like us, you can't do that with just one player. Isak is doing his job by completing chances, but he is also happy that the players create those chances," Howe said.
The balance and structure were found when Howe moved Sandro Tonali to the defensive midfield role, allowing Bruno Guimaraes to move freely up the pitch.
Since that change, affected by a 2-4 defeat to Brentford in early December, the match that Guimaraes called Newcastle a mess, the "Magpies" have won all 6 matches in all competitions.
With Isak's rise to become one of the world's top strikers, the question is, where will his next destination be? How much money will they have to pay? And is that club Arsenal?
