The 2009–10 season was Inter Milan's 101st in existence and 94th consecutive season in the top flight of Italian football. This was manager José Mourinho's second and final season with the club, before his departure to Real Madrid. Inter had the greatest season in their history, winning Serie A for the fifth consecutive season on the final matchday, the Coppa Italia, and the UEFA Champions League for the first time in 45 years, completing a historic treble. Inter became the sixth European club to complete a treble and the first and only Italian club to achieve this feat to date.
