World Cup favourites Brazil will be expected to defeat Mexico in the second round of Group A matches in Fortaleza but their Latin neighbours have no reason to feel overawed.
The Mexicans have 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.
Mexico will also be encouraged by a rain-sodden 1-0 win over Cameroon on Friday when they received fantastic support from their travelling fans.
The home side, however, have won 22 of the 38 previous encounters including the most recent match almost exactly a year ago in the same stadium in the Confederations Cup when Brazil romped home more comfortably than the 2-0 scoreline suggests.
