Although they may not perform all phases during the game, liberos have a very important role in receiving serves and defending the court, and they also participate in raising the ball for a dunk. Because of this, the coaches consider them to play a very important role in the team. The study aimed to determine personal perception of 28 liberos regarding their player role in volleyball and included Croatian female volleyball players who compete at the highest level – Superleague, whose mean chronological age was 20.89±3.30 years. It is a representative sample because, since each team has two liberos in the registered lineup for the competition, all libero players were included. Using the new-constructed anonymous questionnaire Liberos' perception of their player role in volleyball, senior volleyball players assessed their motivation, self-confidence, sense of responsibility, success and satisfaction with their status, their perception of the coach's influence and behavior, and the importance of psychological preparation for their player role. Liberos assessed their role as very responsible, extremely important, and with great personal contribution, and they scored high on motivation, self-confidence, and responsibility. They expect personal advancement and psychological support, which is not adequately provided by professional staff in the clubs.
