Question: Of the two players who each scored first for Brazil and Chile, whose birthday falls earlier in the year? Passage:Brazil faced Chile in the round of 16, taking an 18th-minute lead through David Luiz's first goal for the Seleção. With no further scoring after Alexis Sánchez's equaliser, the match went to a penalty shootout. Brazil prevailed 3–2, with Neymar, David Luiz and Marcelo converting their kicks, and goalkeeper Júlio César saving from Chileans Sánchez and Mauricio Pinilla. The team again faced South American opposition in the quarter-final, defeating Colombia 2–1 with goals from central defenders David Luiz and team captain Thiago Silva. Late in the match, Neymar was substituted on a stretcher after Camilo Zúñiga's knee had made contact with the forward's back. Neymar was taken to hospital and later diagnosed with a fractured vertebra, which ruled him out for the remainder of the tournament. Prior to this, Neymar had scored four goals, provided one assist and been named man of the match twice. Brazil faced further problems ahead of their semi-final against Germany, as Thiago Silva was to serve a one-match suspension for receiving his second yellow card of the tournament in the quarter-final. The Seleção went on to lose 1–7 to the Germans, their biggest ever defeat at the World Cup and first home loss in a competitive match since 1975. Towards the end of the match, the home crowd began to "olé" each pass from the German team, and booed their own players off the pitch after the final whistle. The match has been nicknamed the Mineirazo, making reference to the nation's previous World Cup defeat on home soil, the Maracanazo against Uruguay in 1950, and the Estádio do Mineirão in Belo Horizonte where the match took place.
