Argentina v. South Korea

I'm watching Argentina play South Korea. It's 2-1 in favor of Argentina at the half. A Korean player scored an own goal (in Argentina's favor) when a crossed ball went off his shin into the goal. As a former defender, I am reminded of what I used to tell myself, "If you can't make a clean play on the ball, then get out of the way." You're part of a team, and sometimes (most of the time) you have to rely on other team members. You can't do everything yourself.

Just before half a South Korean player running at full speed seized on a ball played carelessly by an Argentine defender, dribbled it up to the goalkeeper and scored. An example of a mental lapse and mental alertness by different players and the possible consequences of each.
