Chile X Brazil
Alexis Sanchez has an oversize task on his shoulders, as Chile will try to beat Brazil at home, and reverse a bitter history of three World Cup final defeats, including one in Santiago, in 1962. As for Neymar, this may be his most defining moment yet, to either send Brazilians home or on to the next thriller.
Colombia has been beating all odds and may accomplish today what none of its previous national teams have done: getting to the final eight. For Uruguay, on the other hand, only a victory will erase the huge bloody stain left by its serial biter, Luis Suarez, who may never play another World Cup again.
