While I wouldn't go so far as to call it an "upset", Arsenal's 2-0 defeat of Bayern in London a couple weeks ago definitely registers as one of the surprise results of the Champions League so far this year. I mean, Arsenal are a good team, but their two matches pre-Bayern didn't exactly inspire confidence that Arsenal could get anything off Bayern, even at home.
And yet, here we are, resuscitated - Arsenal are still third in the group, with three points from three matches, but those three points taken from Bayern were a huge lifeline and put Arsenal in a good position to advance from the group stages. But to do that, they still have work to do, starting tomorrow in Munich.
Given who Bayern are, it may be too much to hope to roll into the Allianz and take all three points, but the Arsenal who show up tomorrow will be a team with renewed confidence, who have won five straight games in the Premier League, and who are playing with more confidence and certainty than they did early in the season.
Of course, this team is also somewhat hobbled by injuries - expect Joel Campbell to get another start, and hey look JEFF was training with the grownups today (although he almost certainly won't start) - and it remains to be seen, excellent result against Swansea aside, how this patchwork side will hold up against one of the most talented, powerful, and relentless sides in Europe right now.
I don't really have a read on this game; I don't think Arsenal will get slaughtered, but they have a big task in front of them tomorrow. A point would be amazing, and would put Arsenal in good shape to advance. So let's get a point.
