As everyone is speculating, I’ll give it a try as well. Might have a different perspective as I’m not English.
I don’t see Isak leaving England anytime soon. He’s already played in Germany and Spain, and clearly his been the most happy in England. Of course he would smash it there now as well. But the style of play in PL suits him great, and he knows that.
Why would he want to go to France and spend his best years in a one club league? He’s too smart for that.
He has now finally proven himself, and gotten the appriciation here. I have a very hard time seeing him wanting to go back to Spain this summer.
Add to that the fact that the PL is by far the most popular league in Sweden, he’s been born and raised to think it’s the place to be. And it is the biggest scene.
Man U, Liverpool and Arsenal are the ”biggest” clubs for most Swedish kids as well. Don’t really think Man U is very alluring at this point though.
With that said, I actually think he’ll stay. He seems to like it and I think he values that more than some people think on here. Wouldn’t even be surprised to see one of the cup throphies and a top four finish for Newcastle already this season (bar injuries on Tonali or Isak).
