Ronaldo has played for both FC Barcelona and Real Madrid in Spain. Real Madrid signed Ronaldo in 2002 for €46 million. He spent five seasons with Real Madrid from 2002 to 2006 and played 177 games with them while scoring 104 goals. In the 2004-05 season, Ronaldo had 24 goals to his name in 45 matches.
However, injuries ruined his career. He had stop-start campaigns. He played only 27 games for Real Madrid in the 2005-06 season. A massive decline in the numbers tells you what happened. The woes only increased the next season. The inclusion of Nistelrooy in Real Madrid meant Ronaldo became a liability at the club.
The Brazilian legend barely played only 14 games in that season. He left Real Madrid at the end of the season and joined AC Milan.
