Isak is a great striker, I think he would definitely be great for Arsenal, they are going to need some help up front. People always talk about how a team has this position locked or that position great, but you always need more players in positions so that you could have alternatives, and you could always plan for the future as well.
I had such discussion with a close pal but he didn't see things the same way which I did anyways. When I looked at the players recently brought in by Mikel Arteta after Manchester City leapfrogged them to finally win the Premier League Competition, they made significant signatures that turned things around.
I looked at introduction of Declan Rice from West Ham United, Trossad from Brighton and then David Raya from Brentford United. These are obviously players who had experience already in the Premier League and settled in completely and speedily immediately they was signed into Arsenal.
The same could still happen for Isaak but, Arsenal haven't made anymove for him. Players they signed from the Premier League Competition are ready to make quick impact and I'd love to see him bringing the swedish international. The most important thing is the Premier League Competition and not the Champions League Competition. Hopefully they chase the right chase.
