PSSI (the All-Indonesia Football Association) is prioritizing the development of strong mental resilience – a “steel mentality” – within the Indonesian national football team. Vice Chairman Ratu Tisha expressed this ambition, highlighting the importance of psychological strength for future success. She believes that fostering this “mental baja” is crucial for improved performance on the international stage. To achieve this goal, Ratu Tisha is advocating for increased scientific research focused on sports psychology and its application to football. This research will inform strategies to build a more mentally tough squad capable of handling pressure and performing consistently. The initiative signals a shift towards a more holistic approach to player development, recognizing the crucial role of mental conditioning alongside technical and tactical skills. Ultimately, PSSI aims to cultivate a national team renowned not only for skill, but also for unwavering determination and resilience.
