Nigeria have been cruely undone by Argentina in a few WC but this one they didnt play anywhere near as well as their previous game and seemed to choke.
The difference in the last couple of days of this competition the referees have been clearly warning the defenders not to do it. Yet some have decided to ignore these warnings.
I expect the Serbian one did to after that double team rugby tackle they also accused VAR of bias so they kind of had to make sure they cracked down on it.
