Carlo Ancelotti Cavaliere OMRI, Ufficiale OSI (কার্লো আনচেলত্তি) is an Italian professional football manager and former player who is the head coach of the Brazil national team. Nicknamed "Carletto" in Italy and "Don Carlo" in Spain, he is regarded as one of the greatest football managers of all time. Ancelotti has won the UEFA Champions League five times, a record for a manager, and is the only manager to take part in six Champions League finals. Ancelotti is also the only manager to win league titles in all of Europe's top five leagues. He has won the FIFA Club World Cup three times and has won the UEFA Super Cup five times, a record for a manager.

As a player, Ancelotti won two European Cups with AC Milan in 1989 and 1990, making him one of seven people to have won the European Cup/Champions League as both a player and a manager. He played as a midfielder and began his career with Italian club Parma, helping the club get promoted to Serie B in the 1978–79 season. He moved to Roma the following season, where he won a Serie A title and four Coppa Italia titles. He then played for the late 1980s Milan team and won many titles, including two Scudetti and two European Cups. At international level, he had 26 appearances and one goal for the Italy national team. He represented Italy at two FIFA World Cups and at the UEFA Euro 1988, finishing in third place at the 1990 World Cup and being a semi-finalist at the Euro tournament.

Under manager Enzo Bearzot, Ancelotti made his Italy national team debut and scored his first and only goal on 6 January 1981 in the 1980 World Champions' Gold Cup against the Netherlands, which ended in a 1–1 draw. He was very likely to be capped for the 1982 World Cup campaign, but a dramatic knee injury forced him away for several months, as Italy went on to win the tournament without him. He was a part of Italy's squad in the 1986 World Cup, but did not make a single appearance, as both he and Paolo Rossi struggled during the team's fitness tests, due to the altitude of the region, and were replaced in the starting line-up by Fernando De Napoli and Giuseppe Galderisi, respectively.

Under new Italy manager Azeglio Vicini, he was a key member of the Italy squad that reached the semi-finals of UEFA Euro 1988, and was also set to represent his nation at the Summer Olympics in Seoul that summer. An injury to the meniscus of his right knee, however, prevented him from taking part in the tournament, where Italy ultimately managed a fourth-place finish. Ancelotti later went on to play in the 1990 World Cup on home soil under Vicini at the age of 31, although another injury in the first group match against Austria once again limited his appearances in the competition to just three, and kept him on the sidelines until the third-place final against England, in which he returned to help Italy to a 2–1 win. Ancelotti made a total of 26 performances for the Italy national side, and announced his retirement from international football in 1991, making his final Italy appearance under Arrigo Sacchi.

Ancelotti was a midfielder known for his leadership and creativity; he was regarded as one of the best Italian midfielders of his generation. Although he lacked pace and physicality, he was a talented, hardworking, and tenacious player who had excellent technical ability, tactical intelligence, vision, and passing range; his most notable skill being his powerful and accurate shooting from outside the box. A versatile midfielder, he was capable playing several midfield positions. He often played as a deep-lying playmaker, as a central midfielder, or as a defensive midfielder, which allowed him to set the tempo of play after winning back the ball; he was also the mentor and predecessor of Demetrio Albertini and Andrea Pirlo when he was a playmaker at Milan. Despite his abilities, his playing time was cut short by several injuries, which forced him into retirement in 1992 at the age of 33.
