There is a possibility that Madueke will be placed on the left side/Left Winger because Arsenal only have 2 players for that position so Arteta needs new players to anticipate injury problems, while for the Right Winger position Arsenal already has 4 players. From the performance side, Madueke looks fine and he is included in Artena plans to build a young squad and yeah 23 years old Madueke is worth as a future investment.
Two left wingers isn't a small number for a team like Arsenal, although both could be used in every match, with Madueke playing half the game and the other half. However, I see Arsenal's move to acquire Madueke as a remarkable one, as they understand the weaknesses in their current squad. As for the right winger you mentioned, it would be quite sufficient if Arsenal had four players for that position, as three would be more than enough, including to address any injury issues that arise during the season.
Like I always say Arsenal needs a very good striker so in what ever Arsenal is doing they should make sure there signing of a striker is a good one not just a striker but a very good one, a striker that can always score.
Yeah two left wingers isn't a small number for a team like Arsenal but they really need it, you no arsenal players always have injury and so they need as much players as possible to help them stay inform even if a player has injury, last season saka had injury and it really affected the team because saka makes impact when he is playing and they didn't have a player that can replace him.
Next season let's see what Arsenal will do because team not lifting any trophy is something that is really not good at all, I can't blame the coach because his doing his best before he came arsenal was worse so I believe they will get a trophy this season, they should be consistent this coming season because lack of consistency is always there problem.
Well we hope for the best for Arsenal they have really tried they deserve a trophy.
