Nice fake flagging, if you were really a Brazilian you would have understand what they said.
Also no, I don't know if they were saying that, but after hearing the shouting SK player looked in an another direction. Very fishy.
Not saying any SK player heard it for sure, but still shouting positions like the fans of SK did is not cool, it can really be give an unfair advantage.
And of course, this not only apply for SK fans.
