Look at the vote at the top of the topic, not everyone thinks the same as you, and I see that the prevailing opinion is that Arsenal will become champions. I do not agree with this opinion, and I think that last season was the limit of their capabilities for Arsenal, and this time City will not let them be so close. I understand that Arteta really wants to become champions with Arsenal, but as long as City and Guardiola dominate the Premier League, they will be champions. Maybe this is Guardiola's last season in the Premier League, he has not yet decided definitively and will think about it closer to the end of the season.
Arsenal almost won the Premier League for two seasons, but entering the end of the competition, their consistency decreased so that Man City managed to make Arsenal fail to come out as champions. This is Arteta's third season with Arsenal, but to ensure they remain as strong candidates for the title will be very difficult because the Premier League matches have not started. Moreover, other clubs will also make improvements so that the competition will be different from the previous season.
Pep Guardiola has not confirmed whether he will leave after his contract ends next season, but rumors are circulating that he will consider extending his contract. Anything is still possible and we will see next season how Pep Guardiola will make a decision to stay or go because he still has one season left and is focused on bringing Man City back to win the title.
