Mexico coach Juan Carlos Osorio pleaded for the forgiveness of the Mexican people after overseeing one of the darkest days in the country's football history.

Despite a strong show of support from the Mexican locals in Santa Clara, California, Osorio's side put on an abysmal display, losing 7-0 in the Copa America Centenario quarter-final against reigning champions Chile.

The result ended a 22-game unbeaten streak and brought an abrupt halt to Mexico's run at a tournament they had been fancied to win.

"I want to ask for forgiveness from the Mexican people," said Osorio.

"It was an embarrassment. It was a very poor performance from us and I repeat: Many apologies to the Mexican people."

Osorio could offer little in explanation for the defeat, other than to say his team, "made mistakes in everything".

"[Chile] are [ranked] fifth in the world for good reason, but I repeat we had a horrible game today," he added.
