Purpose: Motivation is one of the psychological traits that affects on the athlete’s performance in
sport competitions and has considerable role on identifying and developing talented players.
However, there are limited studies about the effects of internal and external factors on competitive
motivation in professional soccer players. The purpose of this research was to study the effect of
age and the playing positions on the competition-specific motivation in male professional soccer
players. Methods: 59 soccer players of youth U-19, U-23 and senior national teams, who were
selected purposively, completed the Willis’ sports attitude inventory. The data were analyzed by 3
(age) × 4 (position) MANOVA. Results: The statistical analyses indicated a significant main effect
for age (p<0.01), but not for playing position and interaction between age and position (p>0.01).
According to the results of post hoc tests, players of senior national team were more motivated to
avoid failure than youth U-19 national team players (p<0.01). Conclusions: These results may
serve as a criterion for identifying talents and planning psychological interventions.
