2007–08 season
Incumbent European champions A.C. Milan officially confirmed the signing of Pato on 2 August 2007,[4] paying €22 million to transfer his contract from Internacional.[5] Due to FIFA football regulations regarding non-EU minors, Pato was unable to play official matches for Milan until 3 January 2008, when the Italian transfer window and registration reopened.[6] However, Milan was allowed to include the player in friendlies and training beginning 3 September 2007, one day after his 18th birthday. Pato made his non-competitive debut in a 2–2 draw against Dynamo Kiev on 7 September 2007 and scored a header. On 4 January 2008, Pato's transfer to Milan became official.[7]
Pato scored his first Milan goal on his Serie A debut against Napoli in a 5–2 home victory on 13 January 2008. He scored his first brace for Milan, in a 2–0 victory over Genoa at the San Siro on 27 January 2008. He finished the 2007–08 season with 9 goals in 20 appearances (18 in the league).
