Serie A’s most clean sheets market for 2026-27 remains wide open, with no goalkeeper commanding a clear edge as traders price in a cluster of viable candidates around the top of the board. Jean Butez, Mile Svilar, and Mike Maignan sit at the front of the field on the strength of their clubs’ projected defensive structures, but the implied probabilities stay tightly grouped because multiple teams enter the campaign with comparable backlines, recent squad reinforcements, and goalkeepers returning from strong prior campaigns. Historical patterns show clean-sheet leaders often emerge from mid-table sides with organized defenses rather than perennial title contenders, keeping secondary options like Marco Carnesecchi, Łukasz Skorupski, and Vanja Milinković-Savić in the conversation. Pre-season form, early injury reports, and tactical tweaks will likely shift probabilities once matches begin.
