The score says how it ended. xG says how it should have ended: it is the sum of the chances each shot was worth, not an opinion about the game.
A draw, but Lyon created more (2.31 xG against 1.10) — points dropped.
Lyon: +1.8 for the season (2 in the table). Le Havre: −2.4 (18). The gap between points and xPTS is built from matches like this one.
