Brazil have a 84% chance of progressing through the group. An opening match draw against the second-best team in the group is never a disaster so Brazil's 1-1 draw with Switzerland still leaves the Brazilians with an 84% chance of reaching the last 16. That makes Brazil the sixth likeliest team in the last 16 after the opening matches. Brazil do need to record a victory against Costa Rica, though, to stop their chance declining still further.
