Complicated question but i took my time to digest before answering it. Referees as we all have blood running through their veins and mistakes most times are things that makes football interesting. They are bound to make mistakes and these mistakes brought about the introduction of the Video Assistant Referee (VAR) into football. Still yet mistakes happen because their some occasions where the decision of the VAR supercede the of the referee officiating the match and this brings about delay and irrational decisions that carry headlines. Some both parties make mistakes.
