Huh? How can a 3-0 victory over one of the biggest teams in Europe be heartbreaking?
When it's just one goal short of what you need to stay alive in European competition (until penalties, anyway), it is.
Arsenal started out with a magnificent first half and carried that over into the second half, but they ultimately could not cross the finish line, as sloppiness began to enter their game and fatigue caught up with them.
Nevertheless, Arsenal's players played their hearts out today and deserve to be fully commended for their heroic efforts.
As for AC Milan, all that can be really said is that they were very, very fortunate to avoid losing, and they will have to seriously re-evaluate their team mentality after this game. They played like they were already in the next round and came very close to paying for it.
Let's review the lessons learned from what surely was one of the most memorable games in Champions League history.
