Just passing by; Ancelotti was actually a very good footballer

As a player, "Carletto," as he was nicknamed, appeared 26 times for Italy, and participated in the 1986 and 1990 FIFA World Cup, where he was teammates with former club mate and former Italy coach Roberto Donadoni, former Inter Milan coach Roberto Mancini and a young Paolo Maldini.

He started his club career in 1976 with Parma A.C.. In 1979, he transferred to AS Roma, as captain and midfielder, where he won the Italian championship (1983) and 4 times the Italian Cup. From 1987 until 1992 he played for A.C. Milan, and was part of the Milan squad that won consecutive European Cups in 1989 and 1990. During this time, Milan played with one of their finest teams ever assembled in that decade, with Maldini, Franco Baresi, Mauro Tassotti and Alessandro Costacurta in defence, Frank Rijkaard, Ruud Gullit and Roberto Donadoni in midfield and Marco van Basten in attack. His finest moment with Milan was when he received a pass from Ruud Gullit, dribbled around two Madrid players, and netted a powerful long-range shot during the Rossoneri's 5-0 thrashing of Real Madrid in the 1989 European Cup semifinals. He went on to play all 90 minutes in Milan's 4-0 defeat of Steaua Bucharest in the final.
