Think all of this is very silly. Gyökeres is going to end up with 24-25 goals and a Premier League trophy, and it'll be one of the best debut seasons ever for an Arsenal striker. He'll be even better next season.
Havertz by contrast is at his best with another striker on the pitch but can play up top for a while if needed. I think the dynamic is very good and modern, it's exactly the profiles you want for your strikers, the top sides in Europe all tend to end up like this: one classic number 9 and one guy who's in-betweeny.
Havertz's injury record is a concern though, and I suspect Berta and Arteta might consider swapping him this summer, but only if they can get a special player in. I doubt that type of player is gonna be available in the summer though. Keep Kai and Viktor and go in hard for a winger or a midfielder instead, and we're gonna be this far ahead of the rest of the pack again in 26/27.
