Aldair started playing at
Flamengo where he won the State Championship
Campeonato Carioca in
1986. He moved to Europe in 1989, playing with
Benfica, winning the
Portuguese Supercup, and reaching the
European Cup final during his only season with the team. Aldair subsequently moved to
AS Roma in 1990 and played with this club during 13 seasons, until 2003. He played a total of 436 matches with the
Giallorossi, scoring 20 goals in total. During this period he won the
Serie A in 2001, one
Supercoppa Italiana, and one
Coppa Italia in
1991 (also reaching the
UEFA Cup final in the same year). Aldair was recognised in 2000 as one of the best players in the world by being selected in the FIFA XI; still, he remained loyal to Roma in spite of the club not having won any major international honours during his time there. Due to his long career with Roma, Aldair is currently the
most-capped foreign player in the Italian club's history and the club
decided to retire his number 6 jersey when he left the team in 2003. However, this retirement was not permanent, as in 2013 the shirt number 6 has been conceded to
Kevin Strootman, with Aldair's approval. In 1998, he was chosen to be the
captain of the Giallorossi but preferred to grant the
armband to the then 22-years old
Francesco Totti. For his contribution to the club, Aldair was included into the
AS Roma Hall of Fame in 2012, and thus recognized as one of the best footballers in the club's history. After Roma, Aldair then briefly joined
Genoa. In July 2005, Aldair announced plans of playing for
Rio Branco, and played two games for the club in the state championship, helping his team to win the title. Former teammate and good friend
Massimo Agostini convinced him to play in
San Marino for
SS Murata in order to boost their
Champions League campaign. After Murata's dreadful 7–1 aggregate defeat to Cypriots
APOEL in the first round of qualifying for the
2006–07 UEFA Cup, Agostini decided to call upon Aldair to join him on the Italian Peninsula. Aldair took part in the Champions League qualifying stage in July 2007. ==International career==
