While the overall fan mood registered a negligible -0.01 delta, individual fanbases experienced extreme shifts, exemplified by VfB Stuttgart's dramatic +37 surge and AZ Alkmaar's sharp -34 decline. This dynamic highlights a narrative week where localized events drove sentiment more than a stable global trend.
