Mexico face toughest test, warns skipper Marquez

Veteran skipper Rafael Marquez has warned Mexico they face their toughest challenge yet as they attempt to book their place in the World Cup finals second round.

The 35-year-old former Barcelona defender’s claim may raise eyebrows given Los Aztecas, following a narrow victory over Cameroon, have already encountered hosts Brazil and emerged with a 0-0 draw which has left qualification firmly in their own hands.

But, as they prepare for their Group A showdown with Croatia in Recife tonight (9pm), Marquez insists they can leave nothing to chance.
