Cristiano Ronaldo dos Santos Aveiro (Portuguese pronunciation: [kɾiʃˈtjɐnu ʁɔˈnaɫdu]; born 5 February 1985) is a Portuguese professional footballer who plays as a forward for Premier League club Manchester United and captains the Portugal national team. Often considered the best player in the world and widely regarded as one of the greatest players of all time, Ronaldo has won five Ballon d'Or awards and four European Golden Shoes, the most by a European player. He has won 32 trophies in his career, including seven league titles, five UEFA Champions Leagues, one UEFA European Championship and one UEFA Nations League. Ronaldo holds the records for most goals (134) and assists (42) in the Champions League, most goals in the European Championship (14), and most international goals by a male player (111). He is one of the few recorded players to have made over 1,100 professional career appearances, and has scored over 780 official senior career goals for club and country.
Born and raised in Madeira, Ronaldo began his senior club career playing for Sporting CP, before signing with Manchester United in 2003, aged 18, winning the FA Cup in his first season. He would also go onto 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), where he won 15 trophies, including two La Liga titles, two Copa del Rey and four Champions Leagues, and became the club's all-time top goalscorer. He also finished runner-up for the Ballon d'Or three times, behind Lionel Messi (his perceived career rival), and won back-to-back Ballons d'Or in 2013 and 2014, and again in 2016 and 2017. In 2018, Ronaldo signed for Juventus in a transfer worth an initial €100 million (£88 million), the most expensive transfer for an Italian club and the most expensive transfer for a player over 30 years old. He won two Serie A titles, two Supercoppe Italiana and a Coppa Italia, before returning to Manchester United in 2021.
Ronaldo made his senior international debut for Portugal in 2003 at the age of 18 and has since earned over 170 caps, making him Portugal's most-capped player. With more than 100 goals at international level, he is also the nation's all-time top goalscorer. He 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 full 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. He also led them to victory in the inaugural UEFA Nations League in 2019, and later received the Golden Boot as top scorer of Euro 2020.
