Early career Adriano started his career in 1999 on
Flamengo's youth squad and earned promotion to the senior squad one year later. He made his team debut on 2 February 2000, a
Torneio Rio-São Paulo match against
Botafogo. He scored a goal against
São Paulo in the same competition 4 days later. Despite signing a two-year contract with Flamengo in June 2000, he secured a move to
Inter Milan for the
2001–02 season. Inter sold another half of
Vampeta to PSG (ultimately to Flamengo from PSG for an undisclosed fee) for €9.757 million Adriano scored his first goal with the club against
Real Madrid in a friendly match as a substitute.
Parma Adriano was loaned to
Fiorentina for the 2001–02 season, after which a two-year co-ownership deal with
Parma was agreed, for €8.8 million, He formed an impressive striking duo with
Adrian Mutu, scoring 22 goals in 36 appearances. He missed the month of November 2003 due to injury.
Return to Inter Milan Adriano returned to the
San Siro in January 2004 on a -year contract, for about €23.4 million and scored a total of 12 goals in the rest of 2003–04 season. Adriano's was in peak form in the
2004-05 season, where he scored 28 goals and was instrumental in Inter's Coppa Italia victory that year, scoring twice in the first leg of
the finals to help Inter win their first Coppa Italia title in 23 years. In the Champions League, he scored 4 goals and had 3 assists to help Inter into the round of 16. In the round of 16, he scored a hat trick in the second leg against defending champions Porto. He was voted sixth for the
2004 FIFA World Player of the Year. In September 2005, Inter rewarded him for his efforts with an improved contract running until 30 June 2010. He finished the 2005-06 campaign with 19 goals as Inter won the
double, with his most important moments coming in matches against Treviso, where he scored a hat trick in a 3-0 victory, and AC Milan, where he scored twice, including a game winner, in a 3-2 victory. Following the signing of the new deal, Adriano's future at Inter suffered due to poor performances, fueled by questions and speculation regarding his work ethic, which was called into question when he was twice caught partying at nightclubs during the
2006–07 campaign. On 18 February 2007, Adriano skipped a team practice due to effects from a lengthy celebration of his birthday the night before, which led to Inter manager
Roberto Mancini benching him for the team's
Champions League match against
Valencia and subsequent Serie A fixture against
Catania. He finished the campaign with 6 goals in 30 appearances.
Loan to São Paulo in March 2008 On 16 November 2007, Inter owner
Massimo Moratti sent Adriano on unpaid leave to his native Brazil for the second time in eighteen months, where he attended
São Paulo's training center, due to his poor physical condition and a past battle with alcoholism. Though his agent denied Adriano's desire to return to Brazilian club football, Adriano claimed he was willing to leave Inter in the January transfer window in search of regular playing time, with the Italian press stating interest from
West Ham United and
Manchester City. In December 2007, Manchester City owner
Thaksin Shinawatra expressed interest in bringing Adriano to the club during the January transfer window, commenting, "Adriano was a top player, but he lost form when his father died, and he put on weight." Moratti, however, stated that Adriano would remain with Inter. "I would like him back here in January, as strong and as good as he was." On 10 December, Inter technical director Marco Branca said that Adriano was expected to rejoin the team at the start of the new year. "[The] news has been good. We intend to leave him in peace until the end of the programme and then he will be treated like the other players." Inter finalized a deal on 19 December to loan Adriano to São Paulo for the remainder of the 2007–08 season to allow him to compete in the
2008 Copa Libertadores. São Paulo fans were soon seen standing in long lines to buy his new number 10 jersey at the team's official merchandise retailer after Adriano was introduced and his shirt was unveiled at a team press conference. Adriano celebrated his competitive debut with São Paulo by scoring both goals in their 2–1 victory over
Guaratinguetá on the opening day of the 2008
Paulista tournament. He was sent off after
headbutting
Santos centre-back
Domingos on 10 February 2008, and was suspended for two matches after initially risking a suspension of eighteen months. He was fined by São Paulo on 29 February for arriving 30 minutes late for training, then leaving early and exchanging words with a photographer. According to team sporting director Marco Aurélio Cunha, Adriano "left the training ground because he wanted to. The team does not miss him. If he is not happy in São Paulo, he is free to go." São Paulo sporting director
Carlos Augusto de Barros e Silva announced on 17 June that Adriano was returning to Inter ahead of schedule. "We have a balanced squad and it was better for Adriano to go back, given that we won't be able to count on him for the rest of the campaign."
2008–09 season Adriano was a regular goalscorer in the early stages of the
2008–09 Serie A campaign, reaching a combined total of 100 domestic goals in the
