A metric that measures the probability that a pass or cross will result in a goal, weighting each assist opportunity by the xG of the resulting shot.
Expected Assists (xA) assigns a probability to every pass, cross, or set-piece delivery based on the expected goal value of the shot that follows it. A through ball that creates a clear one-on-one would score very high xA — perhaps 0.5 or more. A cross that generates a difficult header from the edge of the six-yard box might score 0.07 xA. The sum of all xA values in a match or season gives a measure of a player's creative contribution grounded in chance quality, not just the number of assists recorded.
xA strips out the finishing quality of the player receiving the pass. A midfielder can create three high-quality opportunities but record zero assists if their team-mates miss the shots — raw assists would give them nothing, but xA would reflect their true contribution. This is why xA is a far better predictor of future assist output than historical assist tallies.
Players who consistently produce more actual assists than their xA are running hot — they are getting fortunate that their team-mates are finishing above expectation from their passes, or the definition of "assist" is capturing tap-ins from their through balls at a lucky rate. Over time, assist output regresses toward xA.
Conversely, a player with high xA but few actual assists is an underappreciated creator whose team is underperforming from his passes. These are prime buy opportunities in fantasy football and prime regression candidates in betting models — their team should convert more of their chances going forward.
xA per 90 minutes is one of the most useful metrics for identifying undervalued midfielders and forwards in fantasy football. A player accumulating 0.3+ xA per 90 over several gameweeks is building up a return expectation that is likely to materialise, even if the assists have not yet shown. Combined with high xG per 90 — players who both create and score — xA helps identify the highest-ceiling fantasy assets.
In FPL, assists score 3 points each, making xA a key driver of expected points for midfielders. Players who are both creating (high xA) and shooting (high xG) accumulate double-return potential. Set-piece specialists — corner-takers, free-kick deliverers — also accumulate xA at an elevated rate due to the sheer volume of deliveries they provide.
xG (Expected Goals)
A metric that scores every shot by its probability of resulting in a goal, based on factors like shot location, angle, and assist type.
xGA (Expected Goals Against)
The expected goals conceded by a team — a measure of defensive quality based on the quality of chances allowed, not just goals shipped.
Progressive Passes
Passes that move the ball significantly closer to the opponent's goal — a key indicator of a team's attacking play style.
Inverted Winger
A wide player deployed on their weaker foot to cut inside onto their stronger foot and shoot or create, rather than cross.
FDR (Fixture Difficulty Rating)
A numerical rating for upcoming fixtures that indicates how difficult each match is for a given team, used to identify favourable fantasy football selections.
