Ronald Koeman (Dutch pronunciation: [ˈroːnɑlt ˈkumɑn] (listen); born 21 March 1963) is a Dutch professional football manager and former player, who is the current head coach of La Liga club Barcelona. He is the younger brother of his former international teammate Erwin Koeman and the son of former Dutch international Martin Koeman. 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.
Born in Zaandam, Koeman began his career at Groningen before transferring to the Netherlands' most successful club Ajax in 1983, where he won the national Eredivisie title in 1984–85. He then joined Ajax's rivals PSV Eindhoven 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.
