Ronaldo

Ronaldo Luís Nazário de Lima (Portuguese pronunciation: [χoˈnawdu luˈiz naˈzaɾiu dʒi ˈlimɐ]; born 18 September 1976), commonly known as Ronaldo, is a retired Brazilian footballer who last played for Corinthians. Ronaldo was one of the most prolific scorers in the world in the late 1990s and the early 2000s. He won his first Ballon d'Or as the European Footballer of the Year in 1997 (aged only 21) and again won the award in 2002 (26 years old). Additionally, he is one of only two men to have won the FIFA Player of the Year award three times, along with French  footballer Zinedine Zidane.

In 2007, he was named as one of the best starting eleven of all-time by France Football and was named to the FIFA 100, a list of the greatest footballers compiled by fellow countryman Pelé. In 2010, he was voted Goal.com's "Player of the Decade" in an online poll, gathering 43.63 percent of all votes and was also included as centre forward in the "Team of the Decade." On 23 February 2010, Ronaldo announced that he will retire after the 2011 season, signing a two-year contract extension with the Corinthians at the same time. He is widely considered by experts and fans as one of the greatest players of all time.
