Bad/mediocre teams sometimes get lucky and take the lead against stronger opponents. They rarely succeed in taking that lead past the finish line, so you shouldn't buy into the hype prematurely. Say what you will about the disallowed goal, but even before Argentina scored and Egypt was leading 2-0, ARG still had way more shots on target, more possession, better passing, and so forth. Japan failed the same way against Brazil after leading 1-0. I hate this sport and only pay attention to it once every four years, usually against my will, and yet I've still seen this happen multiple times. If you play like faggots (Egypt, Japan, etc.), you deserve to lose.
