Playing at home against a weak team and Arsenal can win big with a score of 5-0 indeed, it is bad luck for a striker who can't score a goal. Even though Gabriel Jesus was able to make two assists, but that was not enough because of course as a striker Gabriel Jesus should have been able to contribute in making goals for Arsenal's big win.
This is what I have said before, Arsenal striker becomes a striker who is not very productive, it is quite strange to see how Arsenal's performance so far is not because it is supported by a striker who scores a lot of goals, Arteta should consider strengthening his squad, especially in the attack buy a productive striker to be able to contribute a lot of goals.
what you mean is that Arteta should be looking for one sticker in the January window next year. Indeed, the productivity that comes from every arsenal match is purely not from the stickers but from the midfielders. But I don't believe Arteta will be looking for a sticker in the summer window because Gabriel Jesus is a player who can put pressure on the opposing team so Arteta will be able to save a little money instead of buying other stickers. Saka has also matured this season. I think he is a player who has contributed a lot to Arsenal brilliant performances this season.
