Next season or the next season, but I am sure that this will be achieved if Arsenal continues to try to build this team.
And on the other hand, Manchester City is also quite strong with all its advantages so that it is quite difficult for Arsenal to surpass it.
And what must also be remembered is that Arsenal have not won the Premier League title for 20 years, of course it is quite difficult for them to get it again in the current era with a fairly minimal team mentality, different from Manchester City but everything takes time, let Arteta continue to build this team.
And for Arsenal, they have indeed had quite good improvements in the last 2 seasons since being coached by Arteta but that does not mean it can continue, anything is possible and it will not be easy for Arsenal.
The proof is that 21 years ago was the last time Arsenal won the Premier League title and after that until now they still have the same target but have never been achieved so it is natural if I say that it will not be easy even though in the last 2 seasons they have experienced an increase in team quality.
