Arsenal have improved over time, but they also still have shortcomings that hinder them. In fact, this is the season where they have reached the quarter-finals again after not being able to do so for a long time. But unfortunately they have to face a club that is a nightmare for them every time they meet because several times Bayern Munich have also beaten Arsenal. This season I can't say for sure who will win, but what is clear is that both clubs will perform as well as possible.
Arsenal will not allow their bad record every time they face Bayern Munich to continue. They also definitely want to improve their record when they meet Bayern Munich. Bayern Munich is widely considered to be in decline this season, but in my opinion their decline is not that deep, so they are still very dangerous. Arsenal must be prepared for that.
In this first leg, Arsenal will first play as hosts, they must be able to take advantage of that to enable them to win, because winning will make them more confident in the second leg.
Arteta has built the team's game well, for the second season in a row the team is very competitive and is fighting for the championship, and this season they are performing very successfully in the Champions League. Despite the fact that Bayern are now in obvious decline, this does not make them any less dangerous, especially when it comes to their home matches. Arsenal only need a win at home, even a draw will make the return match very difficult for them, and as the first game against Lazio showed, Bayern can be beaten.
Yes Arsenal are indeed experiencing an improving season, if last season they were not so consistent until the end of the season, this season they are better and they can learn from their weaknesses last season which made them ultimately fail to compete until the end of the season.
as I said before, they need a win in the first leg so they can be more comfortable when they compete in the second leg. That is an initial task that they must complete well, and if they succeed in doing so, then their next task only needs to be to achieve a draw when competing at home to Bayern Munich.
Nothing is impossible, especially as they seem to have learned a lot from what they experienced last season, because last season they were inconsistent and the depth of their squad was not enough to cover when several of their main players were injured. Indeed, a club must be able to learn from their previous weaknesses if they want to improve even better.
