Daei’s coaching philosophy emphasizes discipline, teamwork, and moral integrity — values that mirror his own personality. Known for his high standards, he expects his players to exhibit professionalism, fitness, and respect for the game. At Saipa F.C., his first managerial job, Daei surprised everyone by leading a modest club to the Iran Pro League championship (2006–07) — a feat few thought possible. His ability to motivate players and create a winning mentality was widely praised. Though his later managerial stints at Persepolis, Naft Tehran, and the national team had mixed outcomes, Daei’s impact extended beyond trophies.
He was known for discovering young talent, such as Mehdi Taremi and other future stars, giving them opportunities to grow and succeed. Daei’s entrepreneurial ventures demonstrate his sharp business acumen. He founded Daei Sportswear & Equipment in the early 2000s, which grew into one most recognized sports brands. The company has supplied uniforms and sporting goods to professional teams, including the national team.
