Barcelona’s flawless 9-0-0 start, with just nine goals conceded and four clean sheets through nine matches, underscores their current defensive edge alongside Atlético Madrid’s organized backline and similar tally. Real Madrid trails with only two clean sheets amid ongoing absences for players like Rodrygo, Militão, and Mendy, yet traders assign them the highest implied probability due to historical consistency in shutouts and deeper squad resources over a full campaign. Atlético’s proven defensive structure and Betis or Celta’s early results add further competition, keeping the market bunched as form, injuries, and fixture difficulty evolve.
