Across the 3 2026/27 matches with verified per-match xG, Rio Ave scored 2 from 1.7 expected goals and conceded 3 from 5.2 expected against.
The attack overperformed its chances by 0.3 goals and the defence conceded 2.2 fewer than expected. Coverage is 3 of 10 matches; missing matches are excluded, never estimated.
Covered sample: 2 scored from 1.7 xG, 3 conceded from 5.2 xGA over 3 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.
