That’s probably a big part of the issue. Referees get pressurized so much, dare i say it, by Celtic and Rangers, that their decisions are influenced by it, be that consciously or subconsciously. That might be considered as Mind games by the clubs but when it carries on over into their private life, family members and home, that crossing way over the line.
not really sure what can be done about that as it is more a reflection of the dregs in our society.
