Arsenal's superb performance last season which was surprising to many is as a result of the Mikel Arteta's great work at the club and how the club has grown tactically and in confidence since he took over the managerial role at the club.
This will be the club's first appearance in the competition since the 2016/17 season and as expected they'll do well in the competition but surely not win even when it's still possible.
Arsenal have been heavily criticized over the past few seasons, but Arteta is slowly showing and seems to be saying that he just needs a process that will improve the team's performance. I really understand that because indeed if a club wants to create a good team framework then the process will be long and maybe in the process it will be a lot of disappointment because it doesn't match expectations.
Last season he was able to display a neat game, even he could have led Arsenal to become Premier League champions if only they had not lost stability towards the end of the season.
Next season he should be able to work even better, because in the transfer market he brought in several players who could make a difference to their game even better.
Slowly but surely Arsenal found something that was missing from them a few years ago.
