I admire Arsenal's performance in the Premier League. I haven't anything to say against that. They are even the most scorer team in the league in addition to their being the leader there now. 
But we don't see the same team in the Champions League. I assume you would agree with me on that as well. We can't say their performances here so far have been very consistent. We have all seen how much they struggled against Porto. There is still a point that they can benefit from though. Bayern Munich's performance in the Champions League hasn't been amazing either. If Arsenal manage to make big difficulties for their defense then things can get really interesting.

The Champions League is a really different arena. Real Madrid have done great things in this tournament in the past, even when they were very bad in the league. Arsenal, when they were very good in the league, are not as good as expected in this tournament. The Champions League has a different ambiance. And I have to say that Arsenal vs Bayern Munich is a match I will never bet on. Maybe I will bet on both teams to score a goal. But I think it is very difficult to know which team will win, and which team will advance to the next round.
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.
We need to understand that those seasons that Bayern Munich won Arsenal they were in a more better form as compared to their form this season and lately, Arsenal seems to be a very difficult team to win regardless of the fact that they lost their knockout stage first leg against Porto but they came back in the second leg and Won Porto thereby qualifying for the quarter finals.
You all can agree with me that Bayern Munich is just being hyped in this game between them and Arsenal based on previous analysis but it is obvious that they ain't in their best performance this season but Arsenal is currently in their best form of which they are still filled with so much enthusiasm so the only thing am seeing in that Arsenal may likely win Bayern Munich at Emirate stadium while Bayern Munich will win at their home ground but the highest scorer between the both teams will qualify for the semi finals
