Uncertainty surrounds Brazil team to face ChileScolari wants to keep his side a secret -
Luiz Felipe Scolari is keeping his cards close to his chest ahead of the hosts' last-sixteen World Cup tie on Saturday.
Scolari said: "I do not know the team that will play. There's always one issue or another, we cannot define [the team] because even in normal practice something may happen and you have to redefine [it].
"I will not [reveal the starting line up] early, because as I said we have a workout and someone could get hurt. I have 23 [players], and from the 23 [I will choose] 11 tomorrow."
