About Ronald Koeman
Ronald Koeman (Dutch pronunciation: [ˈroːnɑlt ˈkumɑn]; born 21 March 1963) is a Dutch professional football manager and former player who was most recently manager of the Netherlands national team. Koeman scored over 250 goals whilst playing in defence for the majority of his career. Koeman was capable of playing both as a defender and as a midfielder; he frequently played as a sweeper, although he was equally known for his goalscoring, long-range shooting, and accuracy from free kicks and penalties. Because of his goalscoring, he is considered one of the best attacking center backs of all time. Born in Zaandam, Koeman began his career at Groningen before transferring to the Netherlands' most successful club Ajax in 1983, where they won the national Eredivisie title in 1984–85. He then joined Ajax's rivals PSV in 1986, winning three consecutive Eredivisie titles (1986–87, 1987–88 and 1988–89) and the European Cup in 1988. Ronald Koeman is one of five European players to ever win a treble with their club and a cup with their national team in the same year. The other four players are his teammates Hans van Breukelen, Berry van Aerle, Gerald Vanenburg and Wim Kieft. In 1989, Koeman moved to Barcelona and became part of Johan Cruyff's "Dream Team", helping the club win La Liga four consecutive seasons (1991 to 1994), and the 1991–92 European Cup, where he scored the winning goal of the final against Sampdoria. He moved to Feyenoord in 1995 and retired as a professional player in 1997. At international level, Koeman was one of the stars of the Netherlands national team, alongside Marco van Basten, Ruud Gullit, Frank Rijkaard and Dennis Bergkamp. During his career with the Netherlands, Koeman won UEFA Euro 1988 and played at UEFA Euro 1992, as well as the 1990 and 1994 FIFA World Cups, captaining the team at the latter. In his managerial career, Koeman has won three Eredivisie titles: twice with Ajax (2001–02 and 2003–04) and once with PSV (2006–07). He is the only individual to have both played for and managed the "Big Three" of Dutch football: Ajax, PSV and Feyenoord. Abroad, he had spells in Portugal with Benfica and Spain with Valencia, coaching Los Ché to victory in the 2007–08 Copa del Rey, and managed Premier League clubs Southampton and Everton in the 2010s. He was the manager of the Netherlands national team between 2018 and 2020, finishing runners-up in the 2019 UEFA Nations League. In August 2020, he was appointed manager of Barcelona, with whom he won the 2020–21 Copa del Rey, but was sacked in October 2021, following a poor start to the new season. In 2023, he was reappointed as the manager of the Netherlands national team. He decided to step down as manager of the national team shortly after the unsuccessful 2026 FIFA World Cup.
