From 2003 until 2006, he played for English Premier League club Middlesbrough, winning the 2004 League Cup and finishing as runner-up in the 2005-06 UEFA Cup. He retired due to a misdiagnosed heart condition while playing for Brazilian club América-SP in 2007.
Doriva began his career at the youth of São Paulo Futebol Clube, and after spending 1992 at Goiás teams Anapolina and Goiânia, was promoted to the main team under coach Telê Santana in 1993. That same year he won both the Libertadores da América and the Intercontinental Cup. In 1995 he was transferred to XV de Piracicaba after having his rights purchased by then-owner Rolim Amaro, founder of TAM Airlines.
Doriva came to Atlético Mineiro in 1995, as the team had just gotten a sponsorship deal with TAM. There Doriva had what he considered crucial years in his formation as a player, leading to a $4 million sale to FC Porto.
Porto, Sampdoria and Celta Vigo
Doriva's career in Porto had three Primeira Liga titles before he opted to transfer to Italy's U.C. Sampdoria, in a $8 million four-year contract. In 2000, he went to Spain, playing for Celta Vigo.
After five appearances for the club, Doriva was given a one-year contract with Middlesbrough on 21 July 2003. In his first full season at Middlesbrough, Doriva was first choice in midfield alongside George Boateng. He found his chances limited after this, however, due to the emergence of Stewart Downing and the conversion of Boudewijn Zenden to central midfield. On 29 February 2004 Doriva started as Middlesbrough won their first major trophy, the 2004 Football League Cup Final, with a 2-1 win over Bolton Wanderers in the Millennium Stadium in Cardiff. His only goal for Middlesbrough came in a 2–1 victory at Notts County in the third round of the FA Cup on 8 January 2005.
In 2005 he earned a one-year contract extension, which Middlesbrough allowed to expire in July 2006.
Following his release from Middlesbrough, he then signed for América-SP in Brazil, where he had a heart problem detected. Doriva's father and grandfather both died from heart conditions, and therefore he decided to retire from playing. Subsequent tests showed that the diagnosis was inaccurate and he could have continued playing, although he remained retired.
After retirement, in 2009 Ituano Futebol Clube president Juninho Paulista, who played with Doriva in both Middlesbrough and São Paulo, invited his friend to work at the team. Following some time in the team's youth clubs and as an assistant coach, in 2014, Doriva became Ituano's coach. He led Ituano to a Cinderella run on the Campeonato Paulista, winning the title on penalty kicks over Santos.
Doriva's first cap for the Brazil national football team happened in 1995. He was part of the Brazil squad which reached the final of the 1998 FIFA World Cup. He wore the number 17 shirt and made one appearance, in the second match of the group. He came on against Morocco in Nantes as a 68th minute substitute for César Sampaio. He played a total of 12 games for the Brazilian squad.
