Point of correction, Arsenal has quality forward players, maybe if you had said that they lacked depth I would agree with you easily. As per the attacking midfieder, they have Odegaard and he's still young and vibrant right now. Instead of splashing such figures on Florian Writz, th y should rather go all out for Viktor Gyokeres. Thoughts? Look this current Arsenal squad, what they need right now is a complete and proven striker who can convert goals. Maybe Alexander Isaak would be great name to mention too!
It's better to sign Gyokeres rather than Wirtz, what Arsenal need is striker, they don't really need Wirtz even though he's skillful and can play in many positions. Both Wirtz and Isak are already overrated, this will make Arsenal spend more money than they should.Take a look with his statistic, he's always perform in any match, if he not able to score a goal, at least he can give assist. If he can get a good results against Porto and International match, it means he's really that good.
Arsenal urgently needs both of players. I think they want to recruit Wirtz. Their poor performance after Odegaard's injury caused this. They lack of quality in CAM. So, they think Wirtz is their answer to strengthen their CAM.
Also, they urgently need to recruit new attackers. Their current ones are poor. But i think they will put a new CAM as their priority instead of new striker.
