Arteta is an experienced manager and he understands better what the club needs to improve and what qualities to look out for in players. I don’t know about Arsenal fans having mixed feelings about this transfer but I trust they will eventually understand when the season begins.
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.
