Mexico take 5-1 aggregate lead into second leg with All Whites, but aren't complacent MEXICO have vowed to avoid complacency in Wednesday's second leg of their World Cup intercontinental play-off against New Zealand, despite taking a 5-1 advantage into the match. After a dismal qualifying campaign, El Tri finally hit form against the Oceania champions in front of 105,000 fans at Mexico City's Azteca stadium last week. Striker Oribe Peralta, who scored a brace, said Mexico had to maintain the pressure in Wellington on Wednesday and could not afford to take the 79th-ranked New Zealanders lightly. "I know that the score is large for us but we have to try to increase the advantage in the second leg to get the ticket to Brazil 2014," he said. Former Barcelona defender Rafael Marquez said the fact that Mexico had to contest a play-off half a world away from home in order make the World Cup was enough to stop Miguel Herrera's men becoming over-confident. After barely scraping into fourth position in CONCACAF qualifying, Marquez said the chance to qualify against New Zealand was a reprieve the Mexicans were determined not to squander. "Without doubt it's been difficult to see Mexico in a play-off but we're here and we've got to show our best and continue to work hard to ensure we get through," he said. The world's 24th ranked team, regarded as a regional footballing powerhouse, won only two of their 10 CONCACAF qualifiers, scoring a paltry seven goals and shedding three managers along the way.
