I don't know why Arsenal still need a striker at the moment when they choose many strikers who currently have no injury list, is it because Arteta is still not satisfied with the strikers he has now?
Arsenal need a striker with a big name because I think Gabriel Jesus is a complete failure, he didn't meet up with the club objective and aims. He was a big boy in Manchester City but he is not out to use back then and Arsenal needed him to play the 9 but upon coming to the club, on his first 12 matches, he only as scores 5 goals but after he got injury and Nketkiah took over, he score 9 goals in 10 appearance, who do you think is better but they don't value Nketkiah that much.
Nkiteah and Jesus are still quite reliable in addition to there are several adequate left / right wing strikers now, but I don't know the reasons behind the management for example who asked for it but currently Arsenal are still strong with a makeshift squad now.
If Arteta quest to get another good striker from Juventus become successful, they will sell Jesus out because it seems that Juventus are having much interest in buying Gabriel and it's going to be a perfect swap for Vlahovic to get a new striker or they may go for Ivan Tony as their next interest of the striker.
