Ronaldo began his senior career with Sporting CP, before signing with Manchester United in 2003, winning the FA Cup in his first season. He would also go on to win three consecutive Premier League titles, the Champions League and the FIFA Club World Cup; at age 23, he won his first Ballon d'Or. Ronaldo was the subject of the then-most expensive association football transfer when he signed for Real Madrid in 2009 in a transfer worth €94 million (£80 million). He became a key contributor and formed an attacking trio with Karim Benzima and Gareth Bale which was integral to the team winning four Champions League wins from 2014 to 2018, including La Décima. During this period, he won back-to-back Ballons d'Or in 2013 and 2014, and again in 2016 and 2017, and was runner-up three times behind Lionel Messi, his perceived career rival. He also became the club's all-time top goalscorer and the all-time top scorer in the Champions League, and finished as the competition's top scorer for six consecutive seasons between 2012 and 2018. With Real, Ronaldo won two La Liga titles, two Copa del Rey, four Champions Leagues, three UEFA Super Cup and three Club World Cups. In 2018, he signed for Juventus in a transfer worth an initial €100 million (£88 million), the most expensive transfer for an Italian club and for a player over 30 years old. He won two Serie A titles, two Super Coppa Italiaao trophies and a Coppa Italia, became the inaugural Serie A Most Valuable Player and the first footballer to finish as top scorer in the English, Spanish and Italian leagues, before returning to Manchester United in 2021. He left in 2022, after his contract with the club was terminated. In 2023, Ronaldo signed for Al Nassr.
Ronaldo made his international debut for Portugal in 2003 at the age of 18 and has since earned over 190 caps, making him Portugal's most-capped player. With more than 100 goals at international level, he is also the all-time top goalscorer. Ronaldo has played in and scored at 11 major tournaments; he scored his first international goal at Euro 2004, where he helped Portugal reach the final. He assumed captaincy of the national team in July 2008. In 2015, Ronaldo was named the best Portuguese player of all time by the Portuguese Football Federation. The following year, he led Portugal to their first major tournament title at Euro 2016, and received the Silver Boot as the second-highest goalscorer of the tournament. This achievement would see him receive his fourth Ballon d'Or. He also led them to a third-place finish at the 2017 FIFA Confederations Cup, to victory in the inaugural UEFA Nations League in 2019, receiving the top scorer award in the finals, and later received the Golden Boot as top scorer of Euro 2020. One of the world's most marketable and famous athletes, Ronaldo was ranked the world's highest-paid athlete by Forbes in 2016 and 2017 and the world's most famous athlete by ESPN from 2016 to 2019. Time included him on their list of the 100 most influential people in the world in 2014. He is the first footballer and the third sportsman to earn US$1 billion in his career.
