From head to head statistics alone we can see how fragile Arsenal were at that time and it looks like this will not happen again with the current squad. The difference is clearly so big that Arsenal could make things difficult for Bayern Munich. Sometimes there are times when those statistics don't apply and I'm pretty sure Arsenal can be relied on.
The Champions League matchup between Bayern Munich and Arsenal has sparked a lot of interest in the competition, and many people have expressed their opinions and thoughts on how the match will play out despite the clear statistics from their previous meetings. I also believe that this year's Arsenal team is different from the ones we were familiar with when they competed in the Champions League several years ago.
This Arsenal team are not fragile, and no team in the Champions League will find it easy to win them. Their league performance and current position should be a clear indication of how strong and consistent Arsenal is this season, as they fight tirelessly to win a trophy after quite a while. They should not be underestimated by Bayern Munich, but rather considered one of the most formidable opponents in Europe they will face this season.
