Juventus, Inter Milan, and Roma sit in a tight cluster at the top of the 2026-27 Serie A most clean sheets market because each enters the campaign with proven defensive structures, experienced goalkeepers, and strong recent records in limiting goals conceded. Juventus has opened the season with three clean sheets in five matches while conceding just four goals overall, building on its historically low xGA figures. Roma leads the early table with only three goals allowed across its opening fixtures, reflecting continued organization at the back. Inter, the defending champions, maintains a balanced backline featuring additions like John Stones and consistent clean-sheet rates from prior campaigns. These factors, combined with schedule depth and squad depth advantages over mid-table sides, keep implied probabilities closely bunched as traders weigh sustained form against the unpredictability of a full 38-match campaign.
