If you look at Arsenal's performance in the last few games in the Champions League, and especially against FC Porto, they were a bit shaky, I believe, because of lack of experience, when in a big tournament like the UEFA Champions League. So I believe their lack of experience will cost them in this game against Bayern Munich, and Bayern Munich are not a team to be underestimated regardless of their recent performances.
Bayern Munich vs Arsenal will be a tough match when they play in the Uefa Champions League quarterfinal. For me, Arsenal and Bayern Munich's strengths are the same, and they have the same pattern of play, but I think Arsenal is the favorite to win against Bayern Munich in the UEFA Champions League quarter-finals.
