I just didn't think Slovakia could beat Germany by two goals. This was quite an embarrassing defeat for them, as it was their first defeat in a World Cup opening match. They actually played very well, but they couldn't deal with Slovakia's quick counterattacks, which left them overwhelmed, creating numerous opportunities for Slovakia to score.
This is a serious situation for Germany, as they don't usually play this badly. We know their quality at World Cups, but now they're bottom of Group A. They need to improve their performance, or they'll be in danger of not qualifying for the first time.
