There are usually four officials controlling a soccer match: one Referee, two Assistant Referees, and a Fourth Official. In non-professional games, the Fourth Official is usually not present. In some youth games (U10 and below in the US), the offside law is not applied, and so the Assistant Referees are also not used. To confound things more, there is a FIFA sanctioned experiment in the use of two Additional Assistant Referees stationed near the goals (one on each side). There may also be Reserve Assistant Referees who take no part in the match unless an Assistant Referee is unable to continue.
Soccer, Rink Hockey and Cycling are Portugal's national sports.

Soccer referees do not necessarily need to speak multiple languages to effectively communicate with players and officials on the field. However, having knowledge of common soccer terms in different languages can be helpful in certain situations. Referees primarily use gestures and signals to communicate during matches.
