LEVERKUSEN (AFP) - Title-hopefuls Japan will be wary to avoid a potential upset here on Friday (today) when they meet a Mexico side riding high in confidence in their second Group B match at the Women's World Cup. The Mexicans pulled off one of the surprises of the tournament so far by holding England 1-1 in Wolfsburg to achieve their first-ever point in their second World Cup. The goal may have been a freak long-range effort from forward Monica Ocampo but it was only the second achieved by the Central Americans in the world tournament after veteran Maribel Dominquez 12 years ago. Although Japan coach Norio Sasaki's 'Nadeshiko' are atop Group B after an assured 2-1 win over New Zealand in Bochum, he knows his side face a fight against a team they have played in friendlies and qualifiers in recent years. "Mexico are very technical. It will not be easy," said Sasaki. "In recent years Mexico have gained power and improved. We feel it won't be easy." For the Mexicans, the point gained was a huge leap forward as they remain in the running for one of the two group tickets for the quarter-finals. "We have taken a great step," said midfielder Nayeli Ranger.
