During a derby game in 1950 against Union Luxembourg, Rewenig was singled out in the match analysis by the Luxemburger Wort, who commended his "great play for forcing a fair draw", noting that every attack from Spora came from him despite difficult playing conditions with frozen snow on the pitch. He received plaudits for his "wonderful technique right up to the final whistle", where he helped secure his team a 2-2 draw.^[1]
