Mexico manager Miguel Herrera is a very passionate man. He's not afraid to let his emotion out on the sidelines.
As his team took on Cameroon in their World Cup opener, Herrera ran the full gamut of emotions. He was angered by bad decisions, frustrated by missed chances and then—finally—elated to see Oribe Peralta break the tie.
Herrera's passionate display in the rain prompted the above GIF to go viral. The GIF itself wasn't from the match, but resurfaced in resounding fashion after his emotional display.
