US national team goalkeeper Tim Howard says he was unhappy with the referees after the World Cup qualifier loss to Mexico midweek.
The Everton shot-stopper believed the referee was intimidated by the crowd at Estadia Azteca in the match the US lost 2-1.
"It seems like when we come to a place like this, the most intimidated person in the stadium is the referee," said Howard.
"The bar was probably tilted in their favor, and that's unfortunate because it was a hard-fought game. We went in hard, they went in hard, and for some reason, we keep coming out with the foul."
