However, Mexicans will not be overawed, having won big matches against Brazil before, beating them 4-3 in the final of the Confederations Cup in 1999 and more recently in the Olympic final in London.
Although that game was not a full international, the match featured several players expected to line up in Fortaleza including Neymar, Oscar and Thiago Silva for Brazil, and Oribe Peralta, the striker whose brace gave Mexico a 2-1 victory.
It gives Brazil pause for thought as they seek their 11th consecutive win.

The hot favourite to replace him is Chelsea star Ramires, who already did well as a substitute in the 3-1 win over Croatia on Friday. Another alternative is Bernard, who replaced Hulk during the closing stages of the same game.
Mexico have no injury concerns after their 1-0 win over Cameroon at a rainy Arena das Dunas in Natal, with goalscorer Oribe Peralta likely to continue up front alongside Giovani dos Santos.
