Expected goals (xG) is a metric used to determine how likely a player is to score a chance and to calculate how many goals a team is expected to score in a match. The metric was invented in 2012 by Opta's Sam Green and has become commonplace across football analytics. In xG, every shot a player has is given a score between zero and one.
