Early years / Roma
Born in Caieiras, São Paulo, Assunção began his career at Rio Branco Esporte Clube, where he stayed two years. He then played for Santos FC, scoring three goals in 33 Série A games and moving to Clube de Regatas do Flamengo in 1998.
After impressive performances with Flamengo, Assunção was bought by Serie A's A.S. Roma for 1999–2000. In his first year, he netted once in 21 appearances, adding another in five UEFA Cup matches; he would be used regularly during his three-year stay, proving himself a threat at set pieces as the capital club lifted the Scudetto in his second season.
Assunção joined Spanish side Real Betis in August 2002, being an undisputed first-choice from the start and scoring several goals from free kicks. His debut as a Verdiblanco was spectacular, as he netted once in a 4–2 away win against Deportivo de La Coruña through a 40-yarder with his weaker left foot, then proceeded to strike the woodwork on no less than three occasions; he scored eight goals as the Andalusian team finished fourth at the end of the 2004–05 campaign, subsequently qualifying for the UEFA Champions League.
On 25 July 2006, his 30th birthday, Assunção became a citizen of Spain due to his time spent at Betis, but the 2006–07 season would be however his last in the country. On 22 August 2007 the player left Betis by mutual consent, having failed to fit into Héctor Cúper's plans – he gave a press conference in which he said goodbye to the club and fans, saying that he would not join another Spanish club.
In the following two years, Assunção played in the United Arab Emirates, consecutively with Al-Ahli Dubai F.C. and Al Shabab (Dubai). On 26 September 2009 the 33-year-old returned to his homeland, signing with Grêmio Prudente Futebol (formerly Barueri). However, after a mere months, he switched sides again, moving to Sociedade Esportiva Palmeiras on a one-year deal.
Assunção was selected by manager Luiz Felipe Scolari as one of the club's four "leaders", alongside Marcos, Danilo and Edinho. In the season's Copa Sudamericana, he provided one assist and scored from a long-range kick in a 3–0 win against Esporte Clube Vitória (3–2 aggregate win).
In January 2014, Assunção joined Figueirense Futebol Clube after his contract with Santos expired. In April, however, he cut ties with the club, signing a short-term deal at Associação Portuguesa de Desportos in June.
On 2 September 2014, after refusing to stay on the bench in some matches, Assunção had his contract with Lusa terminated.
Assunção made 11 appearances for the Brazil national team during two years. He made his debut against El Salvador, and scored his only international goal against Russia on 18 November 1998 in a 5–1 friendly win.
