If I remember correctly, Cuauh was the one that asked not to be called up for the confederaciones '05.
Correct that was the last straw for lavolpe. At least he used that to make his point. The relationship was not good but cuah not going to confederaciones was the last straw
Yep This is what caused Lavolpe not to call him up anymore and not take him to the WC the following year Such a petty move
