ABSTRACT
The referee is charged with responsibility for implementing the rules of the game and guaranteeing that players abide by its regulations. These requirements mean that the referee is obliged to keep up with play to be in a good position to notice infringements. In addition to this requirement for mobility about the pitch, the referee must also maintain mental concentration and make split-second decisions about competitive incidents. In many circumstances, he or she has recourse to consult one of the two assistant referees (linesmen).
