When reading historical matchday programmes, the true significance of an event is often hidden behind its official marketing. On page 29 of the August 2014 edition, FC Groningen announced an upcoming friendly match during the October international break. The headline read: “FC EREGAST BIJ ROT-WEISS ERFURT” (FC guest of honor at Rot-Weiss Erfurt).
The text frames the match entirely around nostalgia. The German club had invited Groningen to play a farewell match at their old Steigerwaldstadion before a massive renovation. The connection? Exactly 23 years prior, in 1991, Rot-Weiss Erfurt was Groningen’s very first opponent in the UEFA Cup. The club marketed this October 8th trip as a beautiful journey down memory lane, a chance to celebrate the “old times.”

However, thanks to our chronological digitization of the archives, we know the real historical weight of this friendly. As manager Erwin van de Looi would reveal in a later programme, this exact match in Erfurt was the secret laboratory where he abandoned the traditional 4-3-3 and tested the 4-4-2 system for the very first time. What the fans thought was just a meaningless, nostalgic kickabout in Germany was actually the tactical birthplace of the team that would win the KNVB Cup seven months later.
A Look into the Future
By 2026, the 1991 UEFA Cup tie against Rot-Weiss Erfurt remains a cherished piece of club trivia, but the 2014 friendly has taken on a mythical status among tactical nerds. It proves that football history is rarely made in front of the cameras; it is forged on cold Wednesday nights in provincial German stadiums. The 1-1 draw they played out that evening gave Van de Looi the confidence to implement the 4-4-2 in the Eredivisie, forever changing the destiny of FC Groningen.
