Brasilia: Alexis Sanchez and the pace of Chile's forwards pose the major threat to Brazil's World Cup chances ahead of Saturday's last 16 meeting between the South American rivals, according to Brazil defender David Luiz.
"I wanted us to get through and now I am happy," said the 27-year-old after the Selecao beat Cameroon 4-1 in Brasilia on Monday to seal their place in the first knockout round.
Of Saturday's impending clash with Jorge Sampaoli's impressive side in Belo Horizonte, he added: "Chile are a team who deserve to be there. They have a philosophy of playing good football. They have lots of pace and excellent players."
