For Arsenal, victory is certainly very important for them to get, even if only by a narrow score of 1-0. This victory makes Arsenal have locked a ticket to the next round in the Europa League.
Arsenal have won many games this season by one goal or one goal difference. The important thing is to get 3 points. Arsenal know how to finish the game. Arteta knows how to keep it after taking the leading edge. He plays with a tactic accordingly. They look pretty good defensively. This is one of the keys to success.
They don't have much trouble scoring goals. Along with the arrival of Jesus, the contribution of goals comes from the midfielders. After taking the lead in the match, they keep the score by playing with the right tactic. If they spread this throughout the season, they will be very assertive in all competitions. It was important to qualify from the group, they successfully passed. I expect them to perform well in the qualifiers as well.
