There was an interesting news item here in NZ last week about how Stanzar (The group who oversee a Sth Africa/OZ/NZ professional rugby tournament) are upset at captains, not other players, questioning referee decisions, and asking the captains to keep out of referees' faces. I'm not a rugby fan at all, but am impressed with how these players move away from the ref as soon as they are penalised. Maybe this group could give football refs some hints! Maybe an instant yellow if any player apart from the team captain tries to change the ref's decision or moan to him about it.
Absolutely agree 100%.
