Mexico and the United States renew their rivalry on Tuesday when they face each other in the intimidating atmosphere of a packed Azteca stadium with World Cup qualification points on the line.
.
The Mexicans are under pressure after drawing their opening two CONCACAF qualifiers - at home to Jamaica and away to Honduras.
.
The US recovered from last month's defeat to Honduras with Friday's 1-0 victory over Costa Rica in snowy Denver.
.
"It's a huge game," said US coach Juergen Klinsmann.
.
"When you have the opportunity to come to Mexico City and play at a sold out Azteca stadium with 110 000 people - that is what you want to experience.
.
"It's a special game, a big rivalry. We expect a difficult game, an exciting game and we are very confident".
.
Klinsmann's team showed strong character and fight as they battled in dreadful conditions to get three home points on the board on Friday and he will hope for the same attitude in the very different, testing conditions of the Azteca.
.
While Mexico laboured to a scoreless draw against Jamaica, they looked back to their best on Friday, at least for 70 minutes. Striker Javier Hernandez scored two superb goals before Honduras replied with two of their own in the last 15 minutes to snatch a 2-2 draw.
.
With no shortage of criticism from the media and fans, Mexico are well aware that Tuesday is a 'must win' game and are keen to avoid the scenes in the second half of the Jamaica game when their own fans turned against them.
.
"The pressure is on them," said US midfielder Michael Bradley. "At a certain point there is a chance the crowd could turn on them and so we have to understand they will have big pressure to come out and play a good game from the start and we have to know how to deal with that."
Mexico vs USA would surely be an interesting game to watch. The game would be a tough one for both teams
