Ronaldo de Assis Moreira (born 21 March 1980), commonly known as Ronaldinho or Ronaldinho Gaúcho, is a Brazilian footballer who currently plays for Brazilian club Atlético Mineiro and for the Brazilian national team as an attacking midfielder or forward. He is a two-time winner of the FIFA World Player of the Year, awarded to the best player over the year. He won the award in both 2004 and 2005.
"Ronaldinho", the diminutive and term of endearment for "Ronaldo", is accompanied in Brazilian usage by the nickname "Gaúcho", in order to distinguish him from fellow footballer and countryman Ronaldo, who was known as "Ronaldinho" in Brazil beforehand. Ronaldo simply went by his first name upon his move to Europe, thereby allowing Ronaldinho to drop the "Gaúcho" and go by the name Ronaldinho abroad.
Prior to his move to Flamengo, he played for Paris Saint-Germain F.C., FC Barcelona and A.C. Milan. With the Spanish club, he won his first Champions League in 2006 and the Ballon d'Or in 2005. He became a Spanish citizen in January 2007. He was also named in the FIFA 100, a list of the greatest footballers compiled by fellow countryman Pelé, and in the FIFPro World XI consecutively from 2004–2007.
