Talking about Arsenal against Bayern Munich is indeed very interesting, because this season Arsenal managed to qualify for the quarter finals so there are many positive assumptions which have made the public enthusiastic, especially Arsenal fans. Facing Bayern Munich, we were a little worried, but if we managed to overcome this threat, Arsenal had great potential to advance to the final. However based on the advantages of each, I also quite agree that it is difficult to make a choice. Arsenal, playing at home, has a positive record, this cannot be taken lightly by Tuchel troops. No matter how great Bayern Munich is, what they are facing is a team that never gives up. When it comes to the mental readiness of Bayern Munich players, they are definitely more stable, in my opinion this is just a matter of Arteta tactics against Tuchel and Bayern Munich's history of winning in the past cannot be used as a benchmark.
For now, Arsenal has a chance of winning above 45% as hosts and Bayern Munich 27%. I think it is worth noting Arsenal's level of seriousness in welcoming Bayern Munich to the Emirates Stadium.

Yeah Arsenal deserves to be relied on in the first leg as you said, they have a good record when playing at home so I'm not surprised if the winning percentage is 45% but in the second leg match control may be with Bayern Munich Moreover, Harry Kane is there he certainly understands how to face Arsenal because he has been the top scorer in the Premier League several times.
