With Mikel Arteta as coach, Arsenal will go far this season and we understand the pattern of the coach, aiming for goals and winning major titles with Arsenal but I do think it's not yet time. Mikel Arteta have core duties to carry out this season, we totally know the potential development of Gunners this season and exceptionally stunning.
Arteta started from scratch, even I felt doubtful when 2 years went on there was no good development with Arsenal. But I was wrong, Arteta was finally able to prove himself and be trusted again. Arteta was then given the trust and facilities to make several transfers. Although in the end they have not been able to become EPL champions. But if you look at the moment Arsenal is very good. I think Arsenal's target this year is to win the EPL.
You are right that Arteta started from the bottom, he struggled hard to be able to give a better performance with Arsenal, at the beginning many people even doubted and even demanded him to resign from the Arsenal coaching chair because he was considered unable to give his best with Arsenal. However, the management's patience to keep Arteta is now starting to pay off with Arsenal's performance which is getting better from season to season, even in the last 2 seasons they were able to occupy the runner-up position under Manchester City. This season many expect them to be able to break the dominance of Manchester City who have retained the title for 4 consecutive seasons, currently they are a team that I think is also very capable of doing so. As long as they can be consistent and can be better than the previous season.
