I definitely agree with part of your sentiments. But what I’ll throw back at you is we simply need the depth and immediate injection of quality right now.
If you look at our rivals, we’ve got Chelsea who have Hazard, Morata, Pedro, Willian and Batshuayi. And they’re still looking to add Sanchez (rumoured) and Carroll (Conte has always liked the old school striker as a different point of attack when the game is stagnant).
City have Jesus, Aguero, Silva (x2), KDB, Sane, Sterling and they’re still looking to add Sanchez (well they were… and my gut tells me still will).
I guess you catch my drift by this point. We’re literally on Laca, Ozil, Giroud, Iwobi and Welbeck. We desperately need an injection of immediate quality to at the very least bring some impact to proceedings. This current Wenger team lacks any cohesion and seems to rely solely on moments of individual brilliance and in Aubameyang we could have someone who is capable of individual brilliance.
He’s an upgrade on all our attacking talent bar Ozil at this point. And if we sign him, plus a Malcom we’re at the very least stronger than we were when we hadn’t Theo and a disinterested Sanchez.
Just one more thing, I’m not suggesting we’re capable of stockpiling talent to the extent of some of our immediate rivals but we can certainly afford to have more quality and depth across the pitch.
