side West Ham United. AC Milan In early 2008, Leonardo was appointed technical director of his former club AC Milan. Later that same year, he obtained Italian citizenship after 12 years in Italy as a resident. After Carlo Ancelotti left Milan to become the manager of Chelsea at the end of May 2009, Leonardo was named head coach of Milan despite still lacking the required coaching badges (he was set to attend a UEFA A coaching course in June 2009). He was, however, exempted from requiring a UEFA Pro license, which is mandatory for Serie A managers, due to being a former World Cup winner as a player.

Leonardo waved an emotional goodbye to a packed San Siro, as he managed his side's last game with a 3–0 win against Juventus.
