Across the 2 2026/27 matches with verified per-match xG, Olympiacos F.C. scored 1 from 1.5 expected goals and conceded 2 from 3.3 expected against.
The attack underperformed its chances by 0.5 goals and the defence conceded 1.3 fewer than expected. Coverage is 2 of 3 matches; missing matches are excluded, never estimated.
Covered sample: 1 scored from 1.5 xG, 2 conceded from 3.3 xGA over 2 matches.
Expected goals measure the quality of chances created and faced, so a persistent gap between goals and xG marks finishing runs or goalkeeping variance rather than underlying strength. Coverage is stated because partial samples must never masquerade as a full season.
A relative strength index across the covered club cohort, not a percentage or a price.
