I agree with this.
Arsenal don't need an attacking midfielder, what they need is a striker, a quality striker. Gabriel Jesus is not turning u as he should and they need somebody who can deliver. Viktor Gyokeres is a player that most big clubs are keeping an eye on and if Arsenal really means business, they should be going for him. He's expensive, but would be cheaper than Florian Writz.
Arsenal need to take action ASAP, otherwise other top teams will sign Gyokeres. It's not impossible if Manchester United, Liverpool, Barcelona, Milan, or other teams that currently have old/not reliable strikers to recruit him because he's really promising.
If he moved to Liverpool, Arsenal lose two thing, one is Gyokeres and another one is they will face Liverpool with better strength.
It's true that other teams may want to get him, but not sure about United though. Not that United doesn't make stupid decisions, they have been making stupid decisions for a long time now, but they have both Zerke or whatever that new Dutch striker and also Hojlund who I know is injured but will come back.
So they have two strikers they paid good money for already, getting Gyokeres would be a stupid move and would be waste of money when they really need a defensive help and also a defensive midfield help as well, even wingers would be a lot better.
I think Arsenal is the team that needs a striker with the most money right now, any team with more money than Arsenal already has strikers so Arsenal shouldn't have hard time getting him if they want to.
