The mission statement remains the same for the second half as far as I'm concerned; we need to score. That was the case before and it's the case now.
Barca's theatrics, by and large have been handled okay by the ref (his stopping of the game was a strange moment, i think he was thirsty) the yellow cards dished out are par for the course.
Second half coming up and Wenger needs to take a risk. Arshavin? Bendtner?
Score a goal and let's see. One thing he may need to consider is taking of Cesc who is clearly not at his best.
Forty five minutes to make some history. Come on Arsenal.
