The tools used were semi-structured interviews (with focus groups) and document review. To ensure the validity and reliability of the study, the Linoclen and Guba assessment method was used. The paradigmatic model of this research was designed based on the paradigmatic model of Strauss and Corbin. In this research, four categories of financial data analysis, risk modeling and simulation, financial resource management and financial transparency as causal conditions, decision-making process, risk management in contracts, transfer market analysis and the use of technology in financial analysis are considered as the main background factors, internal and managerial conditions, and environmental and external conditions as intervening categories. Also, four factors of increasing financial flexibility, optimizing financial structure, player buying and selling strategies, Forecasting and evaluation were selected as the central category. Considering the set of concepts extracted from the interviews and final codes, the researcher named the sub-category long-term financial strategies, financial awareness and education, and human resource optimization. The final part of the model for improving behavioral biases and optimizing financial management in the transfer season of Iranian Premier League clubs includes improving financial transparency and trust; optimizing resources, and developing financial sustainability in the club.
