In the early stages of the 2026-27 Liga FPD Apertura, the race for the most clean sheets remains tightly contested among Alajuelense, Cartaginés, Herediano, Saprissa, Inter de San Carlos, and others because the season is only a handful of matches old with limited sample size. Traditional defensive standouts like Herediano and Alajuelense bring proven back-line organization and goalkeeper experience, while Saprissa and Cartaginés combine solid recent results with low goals conceded so far. Mid-table sides such as Inter de San Carlos and Sporting have posted competitive clean-sheet tallies in the opening fixtures, and factors like fixture congestion, home/away splits, and minor squad rotations keep outcomes fluid across the full campaign. Trader consensus reflects this balance, with no side establishing a clear edge in defensive metrics or form.
