The tournament hosts have lost just eight of 68 previous meetings with Chile, and have emerged triumphant in all three past encounters in the World Cup, scoring 11 goals in the process.
That run includes a comfortable 3-0 win against Marcelo Bielsa's Chile side at the same stage of the 2010 finals in South Africa, but midfielder Willian insists that Brazilian fans should not automatically expect a repeat performance.
Brazil have yet to live up to the high expectations surrounding them at these finals despite collecting seven points from a possible nine in the group stage.
In contrast, Chile have impressed, notably in sending the holders Spain packing from the competition with a 2-0 win at the Maracana in Rio de Janeiro.
