Sporting Lokeren
In February 1978, Elkjær moved to K.S.C. Lokeren Oost-Vlaanderen in Belgium where he stayed for five years, the longest spell at any club during his entire career. There, he earned two nicknames: "Chefen fra Lokeren" (Lit: The Boss from Lokeren) and "Den Gale Mand fra Lokeren" (Lit: The Crazy Man from Lokeren), surpassing the 100-goal mark in official matches (98 in the Belgian First Division alone).
