MEXICO CITY (AP) — In the end it wasn’t the middling on-field performance by Mexico’s national soccer team that cost Miguel Herrera his job as head coach of “El Tri.”It was the feisty nature, admired by some and criticized by others, that led to the ouster of “El Piojo,” an affectionate Spanish nickname that means “The Louse.”The Mexican Soccer Federation fired Herrera on Tuesday, just two days after he led the team to a CONCACAF Gold Cup title. The ouster came after a television reporter said the coach punched him at the Philadelphia airport.“Nobody can be above a situation like the one that happened Monday in Philadelphia,” said Decio de Maria, who on Saturday becomes president of the federation.“Our values, our principles, are above any result,” he added. “In our profession, our industry, the matches are never over, and as public figures who represent an institution we must be absolutely clear on that.”In a statement, Herrera apologized to his players, staff, fans, the federation and the media for his conduct in “the painful incident I had with a commentator.”“It is clear to me that this is not the attitude that a coach for the Mexican national team should take, despite having received all manner of criticisms, offenses and mockery of my family and my person,” it read.Herrera said he planned to spend time with family and rest.“El Piojo” is the latest to depart from what has become a revolving-door job since Ricardo La Volpe of Argentina was the last to complete a four-year World Cup cycle as Mexico’s head coach.
