Arsenal's performance in the Europa League is unquestionable and also very dominant. Of all the matches they have played, Arsenal has never lost or drawn. The result is always a win. So Arsenal's position at number 1 in the group phase is unmatched.
Especially during the match against PSV, Arsenal looked quite convincing and also dominated the game. Arsenal acted very aggressively and attacked, but unfortunately, his shot was not accurate enough. So from the many total shots, they only scored 1 goal.
what you say is true, all teams have cycles. Liverpool used to struggle to win the EPL and become a resident of the standings mid-table and then become league champions and UCL champions. Now hopefully arsenal can also win the EPL league and the Europa League.
I speak like that because I see it and I need to admit that Arsenal this season has developed in many ways, especially mentally.
