The referee applies the rules of the game and leads the competition in cooperation with the other competition officials

He acts as a timekeeper and takes notes of the competition that are relevant and provides the appropriate authorities with a report of the competition, including information about disciplinary action and other incidents that have occurred, before, during or after the competition.

He also watches and/or indicates that the game is resumed.

Advantage
Allow play to continue if a misdemeanor or foul has been committed and the non-offending team will benefit from the forward play and punish the misdemeanor or foul if the intended benefit, at that time or within seconds, does not follow

Disciplinary measures
The referee punishes the most serious offense in terms of sanction, resumption, physical severity and tactical consequences, when more than one offense is committed at the same time.

He takes disciplinary action against players who commit an offense that should be punished with a warning or a field removal and
has the power to take disciplinary action from the moment he enters the field of play to check it prior to the game, until the moment he leaves the field of play after the game has ended (including penalty kick series).

If a player commits an offence which should be penalised with a field removal before entering the field of play at the beginning of the match, the Referee has the power to exclude the player from participation. The Referee shall report any other improper conduct.

He also has the authority to show yellow and red cards, and, if the competition rules permit, to give a player a time penalty. This from the moment he enters the field of play at the start of the match until after the match including rest, extension and penalty kicks.

To have a good authority and to get players to respect you, it is important to make the right decisions. This becomes a lot easier with referee communication headsets, which allows you to interact with your assistants crystal clear, to make decisions without any confusion
