during Mexico's opening Gold Cup game against Trinidad and Tobago."CONCACAF is extremely disappointed at the discriminatory language chanted by some Mexico fans during their Gold Cup match against Trinidad and Tobago at AT&T Stadium on Saturday, July 10," the federation said in a statement."The 'goalkeeper chant' was heard despite a significant CONCACAF anti-discrimination campaign delivered in recent weeks and extensive efforts [by Mexico's soccer federation] to make clear that it is unacceptable."FMF swiftly condemned the incident and renewed pleas with the fans to stop the chant."We strongly reject any discriminatory act or conduct and we are calling on all those involved to stop these types of manifestations on and off the field," it.
