Mourinho’s breakthrough came in 2004 when he led FC Porto to a historic UEFA Champions League victory. His tactical approach, defensive organization, and ability to motivate players made him one of the most sought-after managers in football. Mourinho moved to Chelsea in 2004, where he won multiple Premier League titles and established the club as a dominant force. His coaching journey continued with Inter Milan, where he won the historic treble in 2010, and later at Real Madrid, where he ended Barcelona’s dominance by winning La Liga in 2012.
