No. I see his creativity as more of creating for himself than making others around him better. (like a better and more productive Martial). From Arsenal, I would pick Ozil ahead of him.
I simply dont think its worth the cost in the long run. If he was younger, I might have a different view.
For me, all moves should be towards winning silverware next season.
I'd take Sanchez over Ozil anyday. Sanchez is one of those players who's able to win games by himself.
We badly need such player, Martial and Rashford are still hot and cold.
Lukaku is more of a target man than a flair player.
I doubt Ibra will stay here next season.
Adding ozil is like adding a better version of Mata to the squad, which is never the priority. Pogba can also play in his position. Mata and Herrera too.
Even Perisic will improve the squad massively imo, let alone Alexis fecking Sanchez. We need a proper winger. And if We sign Sanchez this window, Jose will be able to shift his priority elsewhere (e.g Full backs). It's not like Sanchez is 34 or something.
So this move is also for next season. I don't know why you think it isn't.
