I think Arsenal doesn't have to make a major overhaul to become champions because they already have a pretty solid squad and a good coach. At most, they only need to sign a few players who are really needed and don't have to make changes on a large scale. Arsenal's real problem is that they still don't have the winning mentality that Man City and Real Madrid currently have, and I think if on several occasions they can reach the final, it will form that necessary mentality on its own.
Arsenal is actually on a balance when it comes to squad. It won’t be bad if they want to add extra players to their squad but even with the current squad, they are very much solid to compete with top clubs. The problem I see with them is their relenting attitude when they’re suppose to put more pressure. They normally start very well with good energy but perhaps, the English media hype is one thing that deceive them thinking they have achieved much and begin to slow down their performance and end up losing important points.
You are right, the English media hype is among the things that affect Arsenal, arsenal always starts a season with a good performance but at the end of the season, they will start misbehaving and start performing like a team that doesn’t know how to play ball, the arsenal is among the best teams that have a good squad but still they can’t win a trophy, even a single trophy they can’t win, arsenal don’t know how to win a game and that is one of the best things their coach needs to teach them, arsenal coach needs to learn from Real Madrid on to play a defensive game to win a game, Arsenal don’t need to sign many players this season because they have young and talented players already.
The only thing Arsenal can do is to get another left-win player who can compete with Saka because Arsenal depends on Saka too much and that is why sometimes the player used to play the way he likes, saka needs to have another player who will make Saka feel like he’s not the best player in the squad and sometimes when he is not playing well they will keep him on the bench, arsenal are still playing this season in champion league and many people will be expecting much from arsenal but for me I don’t trust arsenal anymore, the arsenal is not a team that fight to win a trophy.
