After the departure of striker Andriy Shevchenko at the beginning of the 2006–07 season, Ancelotti was forced to redesign Milan's line-up once again, devising a 4–3–2–1 system that would later be known as his "Christmas Tree" formation. Milan's line-up used Inzaghi as a lone striker, supported by attacking midfielders Clarence Seedorf and Kaká, in front of a three-man midfield which featured Andrea Pirlo as a creative playmaker, supported by hard-working defensive midfielders Gennaro Gattuso and Massimo Ambrosini. Milan received an eight-point deduction during the 2006–07 Serie A season for their role in the "Calciopoli" scandal, which virtually put the team out of the title race, and instead led Ancelotti to focus on winning the Champions League. On 23 May 2007, Milan avenged their defeat to Liverpool two years earlier with a 2–1 win at the Olympic Stadium in Athens in the 2007 Champions League final, leading to Ancelotti's second Champions League trophy as Milan coach and his fourth title overall, having also won it twice as a Milan player in 1989 and 1990. During the 2006–07 season, Milan also finished fourth in Serie A, and lost out to eventual champions Roma in the Coppa Italia semi-final. The next season, Ancelotti also won the 2007 UEFA Super Cup, as well as the club's first ever FIFA Club World Cup in 2007, becoming the first manager to do so with a European side. After finishing the league in fifth place, Milan missed out on Champions League qualification, and also suffered round of 16 eliminations in the Champions League and Coppa Italia (to Arsenal and Catania respectively).
