As a North London-born analyst who sees football as an 11-man mathematical game, I watched Porto’s season unravel—not from poor tactics, but from a rigid diamond that refused to adapt. Anselmi’s Opta-driven model ignored spatial entropy; his heatmaps showed gaps where pressure should’ve been applied. The numbers don’t lie: 2 wins, 1 draw, 5 losses. This wasn’t bad coaching—it was data betrayal.
