Yes, but Paraguay have also had quality, something they didn't show this time around in fact they got through because against Qatar somehow Qatar weren't given 2 penalties, I have always liked the way Paraguay plays with all their heart but seems they have lost the quality part. As for missing penalties that is why you put in fresh players in the last minutes, and you make sure they are good penalty kickers. Argentina for a few years were experts at winning at penalties, they aren't so good nowadays.
