Arsenal aren't the same as their 2017 version anymore. They are much more competitive thanks to Arteta's management style. You should be remembering their last draw against Bayern Munich. How it started and how it ended... It wasn't different than seeing a nightmare truthfully. However I'm not expecting a similar result this year.

The reason is not only the improvement of Arsenal team. It is because of Bayern Munich's being likely to be quite unreliable with their game this season.

If you ask which one of these teams would qualify for the semi finals I would pick Bayern Munich though. It is especially due to what I saw in the Arsenal - Porto draw.
