[MEXICO] Argentine coach Guillermo Rivarola has quit as coach of struggling Mexican club Pachuca, one of only two foreign top-level clubs with three Americans on its first team.
Rivarola's exit follows heavy losses to Santos (3-0) and Cruz Azul (4-1) in league play. Pachuca had opened the 2010 Apertura season with a 3-0 win over Club America and 1-1 tie with Toluca.
Rivarola, who had two stints at Pachuca as a player, replaced veteran coach Enrique Meza last summer after Meza's departure for Cruz Azul.
The Tuzos failed to make the 2009 Apertura playoffs but won the 2010 Concacaf Champions League to qualify for the FIFA Club World Cup in December.
Herculez Gomez and Marco Antonio Vidal joined Jose Francisco Torres at Pachuca.
Gomez, who shared the 2010 Torneo Bicentenario scoring title after joining Puebla from MLS's Kansas City Wizards, has yet to score for Pachuca in three games.
Torres was injured and missed the Toluca and Santos games.
Vidal was signed on loan from Indios after its relegation and has played 11 minutes in one appearance.
