This confidence-boosting win was ideal for Arsenal before their first opportunity of silverware against Manchester City at the weekend.
Eberechi Eze looks to be finding his feet as Arsenal's number 10 while captain Martin Odegaard is out injured and his superb strike will only further increase his confidence as the big games keep coming at this stage of the season.
Mikel Arteta spoke before this game about how the experience of previous Champions League ties will help his team as they look to become serial contenders in the competition.
The Gunners boss has transformed the club since he took over in 2019 and this victory over Bayer Leverkusen was their 14th in 17 home games in the Champions League under the Spaniard.
The next step for this impressive team, who have only lost three games in all competitions this season, is to add trophies.
The first chance Arsenal have to break their six-year trophy drought is on Sunday and they will hope that, if they are victorious against City, that it will push them on to win more than one competition this season.
