ɾɐ]; born 19 April 1972), known simply as Rivaldo, is a Brazilian former footballer who played mainly as an attacking midfielder but also as a second striker, and on occasion deployed as a wide midfielder or as a winger. Rivaldo is regarded as one of the greatest, most skillful, and most creative players of all time.
