"He is so authentic, so expressive and so genuine," said Enrique Krauze, a Mexican historian and World Cup commentator. "He's becoming the representation of the Mexicans' ability to celebrate and party. That is very seductive."
Although he wears a suit and a tie, Herrera rumbles up and down the sidelines like a classic Mexican wrestler. When his players score, he shakes his arms in the air and seemingly goes into a state of euphoria, throwing his short, stout body up and down the sidelines.
He jumps atop one player like a friendly puppy, carries another team member in his arms like a proud father or simply kneels down on the sideline, face up, eyes closed, ecstatic.
During the World Cup, sportscasters have affectionately compared Herrera to a cartoon monster -- Tweety Bird's version of Mr. Hyde, from an animated short by Warner Bros. There is unquestionably a humorous resemblance, right down to the shock of sandy hair.
