The 2010 FIFA World Cup South Africa™ qualifier against El Salvador on Saturday will be Aguirre's first match as the coach of El Tri after being appointed in April. Mexico are fourth in the CONCACAF Zone, a play-off position, and beating El Salvador is crucial.
"Javier came to start a revolution in a group which was a little bit broken," said Guardado of club side Deportivo la Coruna. "When you change coaches it is because things are not working properly and because we are not in the top places (in the group). A change makes us try to improve. We think this change could be decisive to get to the World Cup."
"What he transmits is his attitude. His will to win is important," he went on. "It is important that he tells us we can, that we are capable, because maybe we had some doubts in the group. Aguirre removes all the doubts."
Guardado is aware of the importance of Saturday's clash, adding: "It is true Mexico never throw in the towel when things are difficult like this case. We have pride and want to prove we are not the same team that played in the first games of the qualification."
