This week saw a pronounced `perception-performance disconnect` across fanbases, with Los Angeles Galaxy experiencing a significant +25 sentiment surge while AZ Alkmaar plummeted by -20.

Significant `narrative overshoot` was observed, indicating a disconnect between fan sentiment and a proxy for underlying performance. Rayo Vallecano registered the largest divergence at -22.50, suggesting a deeply pessimistic narrative despite potential counter-indicators. Conversely, Nantes showed a positive divergence of +16.40, with GKS Katowice close behind at +16.20, pointing to fan optimism exceeding their current performance proxy.
