This fellow has never played for Brazil. The basic rules are about international football appearances and not the strength of the country you may or may not represent. The arbitration will discuss that this guy having never played for Brazil is as worthy of a permit as, say, Joel Campbell who plays regularly for a much weaker nation.
Let us see.
