This study aims to provide an in-depth study on K-League players' perception and preparation process on retirement. In order to achieve the purpose, data collection was conducted in two major ways; face-to-face interviews and questionnaires from 10 currently working players. The result of study is based on inductive analysis. First of all, sense of expectation and concern, limited scope of secondary job, and necessity for career education are appeared in terms of players' perception. Second, preparation process on retirement is concluded in two categories; personal development activities(non-professional and inefficiency) and financial preparation. Thirdly, difficulties in the procedures of retirement preparation are categorized into ‘limited time and isolated lifestyle caused by staying in club house ’ and ‘lack of educational programs regarding retirement’. Depending on the results of this study, opportunities confined to retired players are supposed to be enlarged to currently working players. In addition, football club and K-League federation need to support players not only to enhance performance but also to prepare retirement.
