As a London-based football data analyst who’s seen it all, I watched Porto’s season unravel not from poor tactics—but from the quiet collapse of leadership. Antesmi’s 21-game tenure ended in chaos: 10 wins, 6 draws, 5 losses. Below the surface, VAR controversies and visual analytics revealed a team losing its soul—not just its position. This isn’t managerial failure; it’s data-driven implosion.
