As were England v Germany 1996, and countless other football games. Varying writers/viewers subjective takes on a match, are secondary to the facts. Cameroon conceded three legitimate goals in a tight game of two quality teams, so deserved to lose.
Defenders bear hugging and shirt tugging is the norm in the PL and Championship. Officials extremely rarely punish it.
Possibly worried that replays will show the attacker simultaneously shirt-tugging on his blindside?
