It is a common sight in football that when a referee calls a foul and shows a card to an offending player, that player as well as other players from the offender's team surround and argue with the referee. What is the motive behind the exchange with the referee?
The three questions I have are
- Can the players make a case with the referee and force him to reverse his decision?
- Is a referee allowed to change his decision of a card after he has already shown it?
- If it cannot be reversed, what do players hope to achieve when they surround and argue with the referee after a card decision?
