25Minutes: Insights. Expertise. Impact.

Coach Kali was very close to becoming a professional footballer. He did not grow up in a Bundesliga academy or a famous youth system. Instead, he played his way into the spotlight through talent and hard work. Clubs like SV Werder Bremen, VfL Wolfsburg and Hannover 96 started to watch him closely.Then everything changed. Serious injouries ended his dream before it could fully begin. In this episode Coach Kali shares his football journey honestely and without filters. We talk about what it really takes to make it, what often goes wrong and what young players rarely get told. His biggest lessons are simple, but powerful: do not change clubs too often, stay patient and grow with your team. Listen to your coach and follow instructions. And take nutrition seriously - talent alone is never enough. After football, Coach Kali had to reinvent himself. Today, he works as a personal coach, fitness trainer and nutrition consultant.*The episode was recorded on November 7, 2025 in beautiful Dubai.Hostey by: Eliel MulumbaAudio editing & mastering: Michael LauderezMusic: hero.created https://www.instagram.com/hero.created/Join conversation on LinkedIn: www.linkedin.com/in/eliel-mulumba-133919147Join conversation on X: Eliel Mulumba (@ElielCyber) / XSend us Fan Mail
