Arsenal seems to be confused about what they are focused on. On the other side, Arteta needs a cover player to replace the long-injured a player like Saka, but on other side, he need a new attacker to cover barren players like Gabriel Martinelli dan Kai Havertz. Arsenal try to recruit Isak, but Newcastle immediately restrict that player to arsenal because both will meet on leg 2 semifinal carabao cup, so if he goes there, that possible will turn things around to be complicated. Now, arsenal must be managed what they were looking for, I think the big problem to fix it asap is the quarterback. Arsenal must recruit new player to replace Saka, and adding ammunition on center fields.
Arsenal are not a rich club and they have limited budget as well as undeep player resource so that Arteta as a head coach, must be well-thought about his plan for the team like what are their main focuses in a season. Premier League and Champions League can be their biggest priorities, and they need to focus on these competitions. Other cups need to be in very low prioritizing ranks and Arteta need to use alternative players, young players for matches in all cups. This will be helpful for the club, coach and players to have best player resources for Premier League and Champions League.
Saka is super important with Arsenal and Arteta need to use this player cleverly, as said don't use him in any cup matches and only use him in Premier League and Champions League. We already saw consequences of overuse Saka recent seasons, he has become more sensitive with injuries, get more injuries, more serious ones, need longer recovery time, and miss more matches for Arsenal.
