Ronaldo, the Brazilian striker who scored 98 goals in 164 games for Madrid between 2002 and 2007, has retired from football. He will be remembered as one of the greatest players in history, managing to overcome a series of severe knee injuries through his sheer and unparalleled talent.
Slate has a good piece up on his retirement, so I won't say too much more, but the article is worth reading.
Ronaldo won a series of club and national trophies, including two World Cups as well as two La Liga titles with Madrid, as well as a staggering number of individual honors including three FIFA World Player of the Year awards, two Ballon d'Or, a European Golden Boot and three Pichichis. He is also the all-time top scorer at the World Cup, and was chosen in the France Football all-time starting XI.
