FC Groningen
Van de Looi's finest hour came in the following year, when FC Groningen defeated Vitesse and Excelsior in the quarter and semi-final of the 2014-15 KNVB Cup to qualify for the final against PEC Zwolle, led by former FC Groningen manager Ron Jans. About 25,000 FC Groningen fans descended on Rotterdam for the club's second overall and first cup final appearance since 1989. The deadlock was broken in the second half of the match, when two assists by substitute Jarchinio Antonia allowed Albert Rusnák to score twice in the span of 11 minutes, giving FC Groningen a 2–0 victory and the club's first major trophy.
