Ronald Koeman is a former Dutch footballer and current manager of Southampton. He is the younger brother of former Feyenoord coach Erwin Koeman and the son of former Dutch international Martin Koeman. One of the best attacking central defenders of all time, Koeman was renowned for his long-range accuracy, especially in free kicks, and is the top scoring defender in world football.

At international level, Koeman was one of the stars of the Dutch national team, alongside Marco van Basten, Ruud Gullit, Frank Rijkaard and Dennis Bergkamp. He won the Euro 88 and played at the 1990 and 1994 FIFA World Cups.

After winning the European Cup with PSV in 1988, Koeman moved to Barcelona and became part of Johan Cruyff's 'Dream Team', and helped Barcelona win La Liga four years in a row between 1991 and 1994, and the European Cup where he scored the winner against Sampdoria in 1992.
