Two good points. When we faced them back in 2009 we let them have only one shot on target. But then again Messi was a different animal, and so too were Essien and Bosingwa. Its for this reason that point 2 you mentioned becomes more important. We have to look to score at least one goal, as keeping a clean sheet at Camp Nou will be difficult. Someone like Torres/Sturridge to burst through their high line on a counter could prove useful.
