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.
