In the ongoing Apertura 2026 portion of the 2026-27 Liga MX campaign, several clubs show comparable defensive metrics that keep the most clean sheets market tightly bunched. Club América leads goals conceded tallies in multiple reports through strong aerial duels won and goalkeeper contributions from Rodolfo Cota and Fernando Tapia, while Toluca, Guadalajara, Querétaro, and Tigres UANL each sit at four clean sheets. León, Santos Laguna, and others trail closely with three or fewer, reflecting solid recent organization amid a schedule featuring varied opponent quality and home/away splits. With roughly half the regular phase remaining plus the full Clausura 2027 ahead, squad depth, injury management, and tactical consistency will determine which side sustains the lowest goals-against rate over the full season.
