Is it about mentality or form of strength which is still considered weak when faced with stronger teams. Of course, the question of mentality is something that is often said, especially in the Champions League. Of course, in the Champions League, every team must be able to exert extra strength when they face a team they have never faced. If you look at the changes made by Arteta, of course he has made great progress in improvement after improvement, but if Arteta continues to fail in bringing trophies, of course in the final assessment he will fail to make changes.
Arsenal target may not be the UCL trophy but they are more focused on the EPL trophy as they did in the previous season. I think they need to lift the EPL trophy first before focusing their strength on the Champions League.
Arteta’s aim is to win trophy for Arsenal next season. The team’s main target is the EPL, they wants to show their quality to win the Premier League ahead of Manchester City because they have gone far; the team is improving massively and yo be a runner up in two consecutive seasons is not easy, they lost the Premier League title in their last match of the season which shows that they can win it next season.
If Arteta can get a better chance to go far in the Champions League, they will do so because Arsenal is in need of all these trophies including the Champions League and any other Cup they will be playing next season.
I don't think they should Focus on UCL besides I don't think they want to focus on UCL... most of their energy will be channelled to EPL next season hopefully they have some luck and get it done or they still f**k it up like they used to do.. Mancity aren't kidding, they are still ready to take the EPL next season so they must fuel each match to bring win in their games for next season. Also they must put it in mind that many teams will also step up their game to win that next EPL ( like Man U , Chelsea..... their major rivalries) .... UCL is gonna be hotter next season
