Early career Koeman finished his playing career with Groningen in 1998 and became youth coach at PSV. In October 2001, he was promoted to assistant manager under
Eric Gerets, and for the 2004–05 season became manager in
RKC Waalwijk. He managed RKC for one season before moving to
Feyenoord. In March 2006, he extended his contract to the summer 2009. However, on 3 May 2007, Koeman announced his immediate resignation due to motivational problems, after a troublesome
season, where Feyenoord eventually finished seventh.
Hungary On 24 April 2008, Koeman became the coach of the
Hungary national football team. On his debut on 23 May, the team won 3–2 at home to European champions
Greece in a friendly; the visitors had not lost since August. The team failed to qualify for the
2010 FIFA World Cup, and Koeman did not win any of his last four games, the final one being a 6–1 loss to his native Netherlands in June 2010; on 23 July he was dismissed and under-20 manager
Sándor Egervári promoted to his place.
Return to the Netherlands Before the
2011–12 season, Koeman was appointed as the new manager of
Utrecht on a one-year deal. Disputes with the board began almost immediately as
Rodney Sneijder was signed without his approval; on 18 October 2011 he resigned. On 17 March 2012, Koeman was hired at
FC Eindhoven, third-placed in the
Eerste Divisie, after
Ernest Faber crossed the city to PSV. After a play-off loss to Helmond, he moved on a two-year deal back to the top flight and Waalwijk for the following season. His second spell at Waalwijk ended in May 2014 with relegation after a 4–2 aggregate playoff loss to
Excelsior Rotterdam.
Assistant manager On 16 June 2014, Koeman was appointed as assistant to his brother Ronald at English
Premier League team
Southampton. The siblings moved to
Everton in the same league two years later. Ronald Koeman was dismissed in October 2017 with the team third from bottom, with most of his staff, including Erwin Koeman leaving with him. On 3 August 2018, Koeman became compatriot
Phillip Cocu's assistant at
Fenerbahçe. Cocu was dismissed at the end of October with the team in 15th in the
Süper Lig, and Koeman became caretaker manager, debuting on 2 November with a 2–2 draw at
Galatasaray in the
Intercontinental Derby. He helped the team into the knockout stages of the
UEFA Europa League, before the appointment of
Ersun Yanal on 14 December.
Oman In February 2019, Koeman was appointed as the new head coach of
Oman, succeeding fellow Netherlands national team member
Pim Verbeek, who had taken the team to their first knockout stage of the
AFC Asian Cup. Koeman signed a two-year deal and was tasked with qualifying the team for the
2022 FIFA World Cup in nearby Qatar. He debuted on 20 March with a 5–0 win over
Afghanistan in the
2019 Airmarine Cup in
Kuala Lumpur, followed two days later with a penalty shootout win in the final against
Singapore. He was fired on 16 December, after a group-stage exit as holders at the
24th Arabian Gulf Cup.
Later career In June 2021, Koeman was appointed as manager of
Beitar Jerusalem in the
Israeli Premier League. He had played with their
sporting director,
Eli Ohana, at Mechelen. He resigned six months later, with his last game being a 2–0 loss at
Bnei Sakhnin. In May 2022, Koeman was announced as an assistant coach to his brother Ronald at the
Netherlands national team, and would commence in the role on 1 January 2023 after the
2022 FIFA World Cup in Qatar. ==Career statistics==
