One of only three men to have won the FIFA World Player of the Year award three times or more, along with Zinedine Zidane and Lionel Messi, and twice winner of the Ballon d'Or in 1997 and in 2002, Ronaldo is considered one of the greatest footballers of all time by experts and fans. Ronaldo scored 62 goals playing for Brazil and is the second-highest goalscorer for his national team. He began the rounds of World Cup tournaments at 17 (three in total: 1998, 2002 and 2006), when he formed part of the Brazilian team that won the 1994 FIFA World Cup. He then went on to play crucial roles at the 1998 and 2002 World Cups, garnering the Golden Ball for player of the tournament in 1998, and scoring twice in the 2002 final, for which he was awarded the Golden Boot as top goalscorer. During the 2006 FIFA World Cup, Ronaldo became the highest goalscorer in World Cup history with 15, surpassing Gerd Müller's previous record of 14. He was forced to retire due to increasing pain sustained from injuries and hypothyroidism.
