The Gunners need a quality material to help them get goals and push them to compete for any title, if I'm to choose among all the strikers you mentioned, I'd go for the Sporting CP striker Viktor Gyokeres or Vlahovic but Osimhen no, we don't know if he might change his mind and play for Napoli since he has been included to the squad for their friendlies.
Not the way you look at it, to find a quality striker is not easy and they're rare. Only few players do the real job of a number 9, and such strikers are not easy to get in recent times. However, Arsenal was never like this in the days of Henry, Van Persie, and Giround they all had other strikers surrounding them, having just one at this time is affecting the club. But Arteta seems to be waiting for a good deal. Gabriel Jesus needs help too, to reduce stress.
Ok let's say I'm not getting the gist but take a good look at how the Gunners are going about business in the transfer market, do they look like a team that knows what they want? Or are they doing the right thing to make the club to be standard and be ready for next season? Letting Thomas Partey gonis another error and they have no better replacement if you ask me. Arsenal have the opportunity to cash in on Gyokeres but they are looking elsewhere when the player wants to play for Arsenal and you can't say they don't have the money, they do and now they choose to go for Hugo Ekitike when they have a promising strikers that wants to join the club and believe me when I say this, Man UTD would do anything to get Gyokeres.
Arteta can wait for the whole month just to get the perfect deal and in the end he'll start the season without a striker, for how long will this continue? Gabriel Jesus is not even sure if he's a striker, when given the opportunity to showcase his best you'd see him confusing himself with bucket loads of mistakes. I feel he should play as a winger not a striker but with him getting injured too often is a problem to the club. As far as I'm concerned the Gunners don't have a striker and it is now or never.
