Not the way you look at it, to find a quality striker is not easy and they're rare. Only few players do the real job of a number 9, and such strikers are not easy to get in recent times. However, Arsenal was never like this in the days of Henry, Van Persie, and Giround they all had other strikers surrounding them, having just one at this time is affecting the club. But Arteta seems to be waiting for a good deal. Gabriel Jesus needs help too, to reduce stress.
Arsenal already have options for good strikers as our age of football, both Gyokeres and Osimhen are both good strikers that can maintain the number 9 perfectly. For goal scorings both strikers are really good at it, only that the team has to pick among them who fits the tactics and positioning, Osimhen and Gyokeres have different pattern of playing their position but the end results is goal scoring abilities.
