Chelsea defender Gary Cahill admits he is only now beginning to realize how badly rival teams want to win the Club World Cup this week, and is taking nothing for granted in Thursday's semifinal against Monterrey.

Chelsea faces the Mexicans at Nissan Stadium having qualified for the tournament as champions of Europe, where the title of world's official No. 1 has traditionally carried significantly less prestige than it does in Latin America.

But with South American champions Corinthians arriving in Japan with a traveling support of thousands, and with four Brazilians among Chelsea's squad, England international Cahill has reconsidered his opinions since touching down at Narita airport earlier this week.
