Team Melli takes on El Tri that will be of great interest to people in my neck of the woods as Los Angeles has a large Iranian population and an even bigger Mexican population. (Just in case you weren't paying attention to population trends in California.)
Mexico is making its 13th trip to the World Cup and has reached the quarterfinals twice, both times when the tournament was in Mexico (1970, 1986).
Iran is making its third appearance in the World Cup and has never gotten out of the first round and has won only one match, a 2-1 win over the USA in 1998. Iran played one of its qualifying matches in Pyongyang, North Korea and won 2-0. North Korean fans rioted over some bad calls, showing that they want to keep up with the rest of the world.
