The complexity of interactions in team sports requires players to have excellent technical skills. The purpose of this study was to longitudinally investigate the predictive value of motor competence (MC) on soccer-specific skills development. Participants were n = 79 boys, aged between 5.89 and 14.63 years at baseline followed for 3 consecutive years. MC was assessed with Körperkoordination Test für Kinder, and soccer-specific skills were assessed with soccer wall-volley, soccer dribble, juggling, and shuttle run with a ball. Hierarchical linear modeling was used to estimate developmental trajectories of proficiency in soccer-specific skills. The final model shows that soccer-specific skills proficiency significantly improved, and that MC was a significant predictor of this improvement. For every point increase in MC, the change in soccer-specific skills proficiency improved to 0.03 z scores each year. In conclusion, MC is a predictor of specific soccer skills.
