With the level that Arsenal has attained this past couple of seasons, there is no team that they can't face even the current European champions Real Madrid or Bayern Munich, Looking at the team there has been a better improvement seen in the team than what we saw when Arteta newly took over, And this season, Arsenal may even have a better performance than what they did in just concluded premier league and Champions League seasons.
Arteta has done an excellent job since taking charge of Arsenal, he has managed to make Arsenal look better than before. Arsenal's squad is also very good, even though their average age is still young, they are able to make Arsenal always a regular team that appears in the Champions League. Arsenal's current weakness is not due to the coach's inability to handle the team, but because they do not yet have a winning mentality.
Arsenal still feels unable to compete when facing big teams, the players' mentality must be improved so that they are better prepared when playing in big matches. Arsenal must be more aggressive in improving the quality of their squad so that they are better prepared to face competition in the UCL. If there are several top players with various achievements, Arsenal might be able to appear in the final and win the UCL title.
It seems that we cannot expect too much from Arsenal in the Champions League although Arsenal have experienced a significant improvement in their current form, in the English league Arsenal only face Manchester City as their strongest competitor at the moment but Arsenal is still far behind Manchester City and made them fail to win the championship trophy, when competing with Manchester City alone they still fail then what can we expect from Arsenal when they Have to face many strong teams in the Champions League so far?
Last season Arsenal was able to perform well in the domestic league so many of us here who favour Arsenal could penetrate the semi-finals, but in fact Arsenal got a defeat to Munich which even in very bad conditions last season, Arsenal champion mentality is one of the problems that should be immediately fixed by Arteta to be able to compete next season both in the league and the Champions League.
