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.
They must understand all the consequences even though it doesn't matter if they are passive enough and don't bring any new players they do in the transfer this season but they also can't protest when their performance remains the same without any changes later.
Arsenal have always played very well in the last 2 seasons because after all we must be aware that their performance tends to increase, but when they don't change their scheme and don't cover the gaps they have I think everything will eventually remain the same where Arsenal's performance will be stuck even though it is still fairly good but there will be no improvement that they have from season to season.
There are still some players who can be considered less contributing especially for their striker problems where Gabriel Jesus and Kai Havertz are still bad if you say one season's performance and that's what they got last season so in this case it would be quite logical if Arsenal were looking for an alternative in several sectors with the aim of lining up some of the vacancies that occurred last season.
