With two of the tournament's goal scorers out because of injuries, coach Raul "Potro" Gutierrez must get production from elsewhere for his team to make the knockout round.
Mexico trained in Brazil's capital Tuesday, a critical session ahead of Wednesday's final Olympic group stage match against South Korea.
The training session was notable for a number of reasons, no least of which because it took place at the installations of Brasília's fire department. It also included Raul Lopez and Carlos Fierro, two players who, like firefighters, have arrived to quickly solve an emergency.
The issue is that two attacking players his side had relied on, forward Oribe Peralta and midfielder Rodolfo Pizarro, will watch Wednesday's match from Mexico.
