Herrera's theatrical gestures are not new to Mexican fans who followed him through his two years as a coach for Mexico City's America soccer club. But his performances on the pitch during the World Cup have won new admirers for the man known as "Piojo," or louse, since he played for Mexico's professional Atlante soccer team.
"Piojo is the way he is and there's no way he is going to change. I am happy they are talking a lot about him," said Mexico's captain Rafael Marquez.
Herrera has more followers on Twitter than other coaches -- 735,000 -- and often posts selfies to his official account, http://twitter.com/MiguelHerreraDT . A favorite is a June 15 snap with a legion of Mexico fans in the background.
"You generally don't hear a lot about the coaches," said Jesus Berumen, 59, a Mexican fan in Los Angeles. "He spreads happiness. He's so natural in the way he does things."
Herrera's overly enthusiastic side hasn't always gotten him positive attention.
