Things to Know:
On 18 January 2007, it was reported that Ronaldo agreed terms with A.C. Milan for a transfer of €8.05 million. Ronaldo was forced to pay for the remaining period on his contract which tied him to Real Madrid, only because the latter did not agree to release him, while Milan were not ready to pay such a sum. On 25 January, Ronaldo flew from Madrid to Milan to watch the team play in a cup tie against Roma. Statements on the club’s website said that Ronaldo was in Milan for a medical, and that a meeting had been arranged for Monday with Real Madrid officials to discuss and finalize his transfer to the Milanese club. On 26 January, Ronaldo successfully completed his medical tests at the Milanello training complex under the supervision of club doctors, and the transfer completed on 30 January and got the squad number 99. He made his debut as a substitute on 11 February 2007, during the 2–1 victory over Livorno. The next game at Siena, on 17 February, Ronaldo scored twice and assisted on a third goal in his first start for Milan, as they won 4–3. In his first season, Ronaldo scored seven goals in 14 appearances. After his move to Milan, Ronaldo joined the list of the few players to have played for both Inter Milan and A.C. Milan in the Derby della Madonnina, and is one of two players to have scored for both sides in the derby game (for Inter in the 1998–99 season and for Milan in the 2006–07 season), the other player being Zlatan Ibrahimović. Ronaldo is also one of the few players to have started for Real Madrid and FC Barcelona, which also boasts a heated rivalry. Ronaldo, however, has never transferred directly between rival clubs. Ronaldo only played 300-plus minutes in his single season at Milan due to recurring injury problems and weight issues. Ronaldo’s only goals in the 2007–08 season, besides his goal against Lecce in pre-season, came in a 5–2 victory against Napoli at the San Siro, where he scored an emotional brace. It was also the first time Milan’s much hyped attacking trio of Kaká, Alexandre Pato and Ronaldo, known as Ka-Pa-Ro, played together. On 13 February 2008, Ronaldo suffered a severe season-ending knee injury while jumping for a cross in Milan 1–1 draw with Livorno, and was stretchered off and taken to a hospital. The club confirmed after the match that Ronaldo had ruptured the kneecap ligament in his left knee. It marked the third such occurrence of this injury, which he suffered twice to his right knee in 1999 and 2000. He was released by Milan at the end of the season, as his contract expired and was not renewed.
