Recent findings (audit lane, verbatim)

Stadion Feijenoord — The 1972 European Cup final was not held at De Kuip; it was held at the Olympisch Stadion in Amsterdam. De Kuip hosted the 1972 UEFA Cup Winners' Cup final and the 1974 European Cup final.

Stadion Feijenoord — The entry states De Kuip hosted the 1988 UEFA European Championship final where the Netherlands triumphed. This is incorrect: the 1988 final was held at the Olympiastadion in Munich. De Kuip hosted group stage matches and the semifinal of Euro 2000, not 1988.

Wembley 1970 — Rinus Israël did not score the opening goal; the opening goal was scored by Tommy Gemmell (Celtic) in the 30th minute. Feyenoord's goals were scored by Rinus Israël (32nd minute) and Ove Kindvall (117th minute).

Wembley 1970 — The claim that Rinus Israël scored in the 5th minute is incorrect; the actual time of his goal was the 32nd minute.

1969: First European Cup Victory — The entry states the year as 1970 in the intro and stats, but the title says '1969: First European Cup Victory'. The correct year is 1970.

1969: First European Cup Victory — The phrase 'The victory in extra time was more than three points' is factually incorrect; the match was decided in regular time (2-1), not extra time.

1984: KNVB Cup Glory — The manager in the 1983–84 season was Thijs Libregts, not Ernst Happel.

1984: KNVB Cup Glory — The final opponent was FC Groningen, not Ajax.

The De Kuip Era: Stadium Legacy — The architect is Leendert van der Vlugt, but the stadium was actually designed by architects Leendert van der Vlugt and Johannes Brinkman (Brinkman is omitted, which is a factual omission).

The 'Feyenoord Boys' of the 60s — The entry claims Eddy Pieters Graafland was part of the squad that won the 1970 European Cup, but the goalkeeper in that final was Eddy Treijtel.

1970 Intercontinental Cup — The entry states the matches were played on 9 and 16 September 1970, but the correct dates are 26 August 1970 (first leg) and 9 September 1970 (second leg).

1970 Intercontinental Cup — [contradicted] The final match against Estudiantes de La Plata took place on October 14, 1970, at the National Stadium in Tokyo, Japan :: The source explicitly states the second leg was held on 9 September 1970 at De Kuip in Rotterdam

KNVB Cups — The entry states the KNVB Cup was established in 1899, but it was actually established in 1898 (the first edition was played in the 1898–99 season).
