Arteta managed to turn Arsenal into a better team than in previous seasons but winning the Champions League requires something much better than what he has done at Arsenal so far.
I think Arteta needs to learn a lot from other European clubs that play in the UCL, there are many things he has to learn to be able to make Arsenal a big and great club that can win the UCL in the future, not this season because they don't seem very ready to compete with other great clubs in the UCL because of course it is very difficult and complicated, Arteta will probably learn more while Arsenal plays in the UCL.
Arsenal's current focus should be on the title race in the EPL because if they succeed in getting the EPL title they can definitely target the UCL title next, as we know, up to now fighting for the title in the EPL is difficult for them and they always fail, how can they dream of achieving it? Fighting for the title in the UCL is clearly impossible. I think Arteta needs to prepare a lot of strategies and the best players in the next season to be able to hunt for the title in the UCL.
In fact, Arteta doesn't need that. He has gained a lot of knowledge from his time as Pep Guardiola's assistant. all Arteta has done is develop the potential he has, to lead Arsenal to be much stronger than last season. and one thing that is on my mind, I am sure that Arsenal is not aiming for the Champions League trophy. Moreover, this is the first time after a long absence from this competition.
I think, if Arteta and Edu are fully aware that there are several strong team competitors in this competition and are very experienced. ideally, Arsenal will just do their best and play as hard as they can in the Champions League competition. If they are lucky they can get past the round of 16, and this is already an achievement for those who have just started competing in this league. the rest, they will focus on the Premier League.
The point is, Arteta must get one of the trophies. Ideally they will target the Domestic League trophy, that way Arteta has met the club owner's desired standards. We know very well how Arsenal's owners are, and only this season they invested in breaking their own record. with the condition that Arteta must present at least one trophy. But, let's just follow Arsenal's journey in this competition. Moreover, the Gunners are one of the teams that I fully support. whether they win or lose, as a supporter I only hope they perform at their best.
