Jorge Sampaoli's men finished second in Group B to set up a last-16 meeting with the tournament hosts and winners of Group A, having beaten Spain and Australia before losing their final group game to Netherlands.
La Roja have shown to be a dangerous attacking team so far in the tournament and, even though they have been eliminated by Brazil every time they have advanced past the group stage of the World Cup, the defender admits his side have to be careful when the teams meet.
"I wanted us to get through and now I am happy," he told Fifa's official website. "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.
"History counts for nothing. We want to win. What is the biggest threat that they pose? The whole team."
Brazil face Chile on Saturday June 28 for a chance to face either Uruguay or Colombia in the World Cup quarter-finals.
