You're 20 yards away from goal and a ball is looping towards you. If you are human -- i.e. not Cristiano Ronaldo -- you bring the ball down, look for a pass and move on with your life. If you are a central defender, you run back as fast as you can.
Apparently, Koichi Aparicio forgot he was both human and a central defender because he decided to hit it and OH MY GOD.
The ball should not be hit that hard. The ball should not swerve like that. The ball should not find the top corner.
