Born in
Rio de Janeiro to a Brazilian father and a
Trinidadian mother, Flores started his professional career with
Fluminense under coach
Carlos Alberto Parreira in 1999. He was the main player in the team's
Brazilian Série C winning campaign, and was the symbol of the restructuring of the club. Parreira once compared him to
Diego Maradona, for having a similar style. After a relatively successful campaign in the
regular series for 2000, in which the team ultimately finished 10th in points, he was involved in a discussion at halftime in the 2nd leg quarter-final playoff game against
São Caetano at the
Maracanã, presumably because he was subbed off the field, and left the stadium.
Fluminense ended up losing that game and being eliminated from the playoffs. They did, however, get to stay in the Serie A for 2001 with their 10th place finish in the João Havelange regular series. In 2004 Flores played for
Brazil, in a friendly match against
Haiti. He scored two goals as Brazil won 6–0. He also played for the
Brazil U-23 team in the
2000 Olympics football tournament. Roger was also eligible for the
Trinidad and Tobago national football team. Roger Flores was transferred to the
Portuguese club
Benfica for a brief six-month period in 2001 for a reported US$6 million. However, he did not adjust and returned to Fluminense (on loan) only 6 months after the transaction. He returned to Benfica in 2002. In 2004, he returned to
Fluminense once again but did not play as well as the previous years. In 2005, Flores was acquired by
Corinthians for a reported US$7 million. In late October 2005, he broke his leg in a 1–1 tie with
Vasco da Gama which knocked him out for the rest of the Championship. He has since recovered from the injury and has been playing again since January 2006. On 13 July 2007,
CR Flamengo signed the player on a six-month loan contract. On 17 January 2008, Roger signed a contract with Grêmio Football Porto Alegrense. In July, Roger signed a contract with
Qatar Sports Club, and left Grêmio. On 4 February 2010, Roger left the
Middle East and signed a contract with
Cruzeiro to play
Copa Libertadores football. == Nicknames ==
