Détári was born on 14 April 1963. He was not even 18 when he played his first game for Bp. Honvéd (Pécs-Bp. Honvéd 1-1). At the age of 19, he already had an unquestionable place in the team. The blond midfielder has suddenly become a favourite of Kispest fans. It was a fabulous career: the national team also depended on him at once. He scored unforgettable goals. Let's just mention his masterpiece scored during a World Cup qualifier in Vienna, or the one from free kick against Poland in Népstadion. In the years to come he collected 61 caps and scored 13 goals in the national team. He was one of those players who were able to decide a match with only one genius movement.
The last time he wore the red and white jersey of Honvéd was on 13 June 1987: Debrecen-Bp. Honvéd 0:2. He was signed by Eintracht Frankfurt. Though he spent only one year in the Bundesliga, he scored a winning goal in the German Cup final. Eintracht sold him to Greek Olympiakos for a record fee of 18 million German Marks. Détári did not succeed in winning the Greek championship with his team, but he helped Olympiakos to claim the Greek Cup title. His next move was to Italy in 1990, when Bologna signed him. He reached the UEFA Cup quarter finals with the red and blue team. In 1992, he was signed by Ancona, where he played 33 games scoring 11 goals. He spent the spring of 1994 in Genoa than left Italy for Switzerland. He won a bronze with Neuchatel Xamax. After this period, he played two seasons for Austrian second division St. Pölten. Later, he returned to Hungarian BVSC, played in lower divisions, but his main focus was on coaching ever since. He trained Oradea for a half year, Csepel for another six months. Following this experience, he was chosen head coach of Kispest-Honvéd and finished seventh with the club.
Though during his playing career, he missed a real great team to play for, he may be revered as the last world class footballer of Hungary.
