I won't be surprised if Arsenal say goodbye to the tournament in this phase. It is still going to be a successful run for them anyway. The opponent is Bayern Munich now and their job is quite difficult. If Arsenal play the same as the Porto matchup then there is a big problem for them. Bayern Munich might seem like they aren't the same as the previous season but they wouldn't be forgiving against vulnerable opponents anyway.
Honestly I don't expect a huge score between these teams this time. Arsenal have made big progress thanks to Arteta. I expect to see them fighting back decently.

But when it comes to my favourite it is still Bayern Munich though.
Everything is possible with Arsenal is currently had depth and quality, but lack of experience is surely going to hurt them which is on Bayern Munich side but now here we have to check few things which are also needed to be discussed Bayern Munich is having not good season and luck is also not on their side for the trophy, so things can go into Arsenal favour which will give them success.
Mikel Arteta bring good strategy which are helping them for having good success and improved of the quality which is much needed even things are tight for the success in this round but still anything can happen Bayern Munich is favourite by many punters because they are feeling secure with their performance in past against Arsenal but still I am giving both teams equal chance for the win in this round.
