I watched Arsenal's matches in EL and in the Premier League, and I will say that Arteta did not spend much energy on EL, either he thought that this was enough for opponents of this level, or this tournament was not very important for him.
After seeing the performance achievements of his players this season, I think Mikel Arteta will continue to use the same game in the Europa League against his opponents later and maybe it is true that he will not be serious for the Europa League this season because they have a more real target, namely winning the EPL title this season. But if Arsenal can also win the Europa League this season, of course it is an extraordinary achievement.
Arsenal's performance is very stable. And if they can continue such a streak of performances in the Europa League then they are capable of winning the title. They have this ability. Arsenal have managed to maintain their dominance in competitive leagues like the Premier League. And all this is possible because of coach Arteta's match strategy. He can make the players confident. And so despite not having many star players, Arsenal is performing well in every match. I think Arsenal will qualify for the Europa League final.
