To be honest, I don't see the progress experienced by Arsenal, but in my opinion, conditions like this are the same as last season, there has been no change whatsoever except in the UCL, Arsenal have had a lot of changes because actually Arsenal was lucky to get an opponent that wasn't too difficult, but after entering the last 8 and in That's when Arsenal had to give up losing to Munich.
Without having to delve into the differences between these two teams, of course Munich's chances of qualifying are very big, but Arsenal's chances of beating Munich are very small and there is almost no chance whatsoever.
In fact, this match has not even been held at all, but we have assumed too much beyond something that cannot be confirmed. well, let's see how these two teams meet and fight to beat each other. so far, we have only seen data and statistics, but the actual match has not been held at all. now if you try to refer to several references, for example the options provided by gambling bookies. for the time being, Arsenal is at odds @2.03, while Bayern Munich is at odds @3.55. well, we can respond a little based on the options that the bookies provide. Here we can see that Arsenal has a chance to beat Bayern Munich in the first leg. Moreover, this match was played at the Emirates Stadium.
Well, I have a different interpretation to what you said. Even though Bayern Munich is more experienced, Arsenal is now different in Arteta's hands. Moreover, Bayern Munich's condition was also unstable. Therefore, this quarter-final match will not be very easy for visiting Bayern as well as Arsenal. However, Arsenal has the advantage of playing at the Emirates Stadium, their home ground. Arsenal now, not Arsenal in the 2017 season. Bayern now, not a very fierce Bayern. So, to find out which team will win, let's just wait for the meeting of these two teams to be held.
