Arsenal shall at least try to bring a quality striker to the club. Nketiah and gabriel are flops now at this moment. This club been linked to the osimhen but it was fake rumor. Arteta has not yet made a move to get a new striker.
Let's wait till mid of summer transfer season.
Last season they did the same thing but indeed Kai also followed and could not develop well at Arsenal even though he was bought with a nominal amount that was not small but indeed Kai's performance was still lacking and needed longer adaptation.
The defense and midfield that Arsenal have this season are still quite good, it's just that sometimes their finishing and attacking lines are erratic because in one match they are sometimes quite good but in other conditions they really can't be expected.
Looking for new alternatives is quite reasonable but they as much as possible have to sell some of their attacking players in order to make their financial stability still maintained especially if you look at their transfer history in the last few seasons they are actually one of the most wasteful clubs in the EPL even though they currently have an improvement in terms of performance but that's all they can get no more because in the competition for trophies they always fail.
