You are still missing my point: the opponents didn't have the quality to test you enough. It doesn't mean your defenses are amazing. Only that the forwards you've faced so far are not top level. If you ignore France, that really didn't even played this World Cup after all, please name a top level striker that played against Uruguay at this World Cup.
Brazil faced Drogba Broke his armand Cristiano Ronaldo He was a lame on this WC so far, and our defenses were able to show their strenghts. Now, we are going to face yet another high level offense, in the likes of Van Persie, Robben and Sneijder,I agree with you on this one. but I believe Lucio and Juan are at a level where they can handle it.
And that is precisely my point: Uruguay remains untested against top level opponents, so you can't really do anything but hope they'll be able to hold the likes of Higuain, Tevez (onside, please. =P), Agüero, Messi, Klose, Ozil, et all.You're talking as if they were god, yet they aren't
