Football Expected Assists (xA) Calculator
Calculate Expected Assists (xA) to evaluate playmaking quality, creativity, and the likelihood of a pass becoming a goal assist.
Pass Characteristics
Analyze the quality of the pass to determine Expected Assists (xA)
Understanding the Inputs
Key factors that determine Expected Assists (xA) value
Pass Type
The technique controls the likelihood of assist.
Through Ball: Highest xA potential (Splits defense)
Cross: Lower xA due to defensive clearance rate
Pass Destination
Where the ball ends up is critical.
Six-Yard Box: Extremely high value (Tap-in zone)
Outside Box: Low value (Requires long shot)
Pressure Level
Defensive pressure affects pass quality.
None: Allows perfect weight/aim (High xA)
High: Reduces accuracy and vision (Low xA)
Receiver Context
The state of the teammate receiving the ball.
Clear: Unmarked receiver has best scoring chance
Marked: Receiver must beat individual defender first
Formula Used
xA = Base Value × Pass Type × Origin Factor × Destination Factor × Pressure × Receiver Ctx
Expected Assists (xA) assigns a probability (0 to 1) to every completed pass indicating how likely it is to become an assist. This calculation considers the starting and ending points of the pass, the type of pass (cross, through ball, etc.), and the defensive context. Professional models use historical data to weight these factors.
Example Calculation:
A through ball (0.35) from the half-space (1.3) into the box (1.0) with low pressure (1.1) to a moving receiver (1.1) = ~0.60 xA (High quality chance created).
Expected Assists (xA) is a football metric that measures the likelihood that a given pass will become a goal assist. It assigns a probability value (from 0 to 1) to every completed pass based on factors like pass type, location, and the resulting shot quality.
Simply put: xA measures the quality of the chance created, regardless of whether the striker scores or misses.
Why Traditional "Assists" Are Flawed
The traditional assist statistic is dependent on the goalscorer. If a playmaker delivers a world-class through ball to a striker who misses an open net, the playmaker gets 0 assists. If a playmaker passes 2 yards to a teammate who then dribbles 40 yards and scores a screamer, the playmaker gets 1 assist.
This creates a disconnection between creativity and reward. xA solves this by valuing the pass itself, not the outcome.
How Expected Assists (xA) is Calculated
Advanced data providers (like Opta, StatsBomb) use machine learning models trained on hundreds of thousands of historical passes. Key variables include:
Pass Origin: Passes from the "Zone 14" (central area outside the box) or "Half-Spaces" are statistically more dangerous than passes from the wing.
Pass Destination: A pass received in the six-yard box has a much higher xA than one received 25 yards out.
Pass Type: Through balls that break defensive lines generally have higher xA than lateral passes or crosses (which have low completion rates).
Defensive Pressure: Is the passer under pressure? Is the receiver marked?
Phase of Play: Counter-attacks often generate higher xA due to disorganized defenses compared to set possession.
"xA is essentially the expected goal (xG) value of the resulting shot, credited to the passer."
Interpreting xA Values
Single Match Performance
0.00 - 0.10 xA: Little creative impact. Mostly safe passing.
0.10 - 0.30 xA: Decent contribution. Created 1-2 half-chances.
0.30 - 0.60 xA: Strong creative performance. Likely created one clear opportunity.
0.60+ xA: Elite playmaking. Dominated the game creatively; arguably deserved an assist.
Season Cumulative Performance
Over a 38-game season:
10.0+ xA: Elite Playmaker (Top 5 in the league).
6.0 - 9.0 xA: Primary creator for a good team.
3.0 - 5.0 xA: Solid contributor or secondary creator.
Industry Benchmarks & Elite Standards
To understand what "good" looks like, we look at the masters of the craft.
Kevin De Bruyne (Man City)
Consistently averages 0.40 - 0.55 xA per 90 minutes. This is the gold standard.
Trent Alexander-Arnold (Liverpool)
Often tops 0.35 xA per 90 from a full-back position, highlighting elite crossing ability.
Lionel Messi (Peak)
Combined elite scoring with 0.60+ xA per 90, effectively breaking most models.
Tactical Applications
1. Identifying Undervalued Players
Scouts use xA to find players who are creating chances but are let down by poor strikers. If a midfielder has 10.0 xA but only 2 Assists, they are likely "unlucky" and represent a huge transfer market opportunity (undervalued).
2. Analyzing Team Strategy
A team with high xA but low goals needs a new striker. A team with low xA but high goals is "overperforming" and likely riding a wave of luck or unsustainable finishing—a warning sign for coaches (regression to the mean).
Improving Your xA Output
For players wanting to increase their xA stats:
Target the "Golden Zone": Passes into the central area of the penalty box (between penalty spot and 6-yard box) yield the highest xA.
Prioritize Cutbacks: Driven low crosses from the byline backwards (cutbacks) have incredibly high conversion rates compared to lofted crosses.
Pass into Space, Not Feet: Through balls allow the striker to shoot with momentum, increasing xG (and thus xA).
Occupy Half-Spaces: Operating in the channel between the center-back and full-back forces defensive errors and opens passing lanes.
Limitations of the xA Model
While powerful, xA is not perfect:
Requires a Shot: Most models only calculate xA if the receiver actually takes a shot. If you play a perfect pass but your teammate slips before shooting, you get 0.00 xA.
Defensive Errors: If a defender miskicks the ball straight to your striker for a tap-in, some models credit you with high xA despite it being luck.
Secondary Assists: xA ignores the "pass before the pass" (pre-assist), often undervaluing deep-lying playmakers like Sergio Busquets or Toni Kroos.
Frequently Asked Questions
Common questions about Expected Assists (xA)
What is the difference between an Assist and Expected Assist (xA)?
An Assist is a binary outcome—you either get it or you don't, depending on whether the goal is scored. xA is a probability metric measuring the quality of the pass. You can have high xA with zero assists (if strikers miss), or low xA with many assists (if teammates score difficult shots).
Does xA account for the finishing ability of the striker?
No, and that's the point. xA evaluates the passer, not the finisher. It assumes an "average" striker receives the ball. This isolates the playmaker's contribution from the striker's finishing performance.
What is a "good" xA per game?
For a creative midfielder, 0.20 - 0.25 xA per game is solid. Above 0.40 xA consistently is elite (world-class level). For defenders or defensive midfielders, anything above 0.10 is respectable.
Why do I have 0 xA even though I made great passes?
Most xA models calculate values only when a shot occurs. If you play a great through ball but the striker is tackled before shooting, or chooses to pass again, no xA is registered for that action. (Some newer "Expected Threat" or xT models attempt to solve this).
Do crosses give high xA?
Generally, no. Crosses have a low success rate compared to ground passes. A typical open-play cross might only have 0.02 - 0.05 xA unless it lands right on a striker's head in the six-yard box. Volume crossing is often an inefficient strategy.
Can xA be higher than 1.0 in a match?
Yes. xA is cumulative. If you create 5 chances each worth 0.20 xA, your total match xA is 1.0. This suggests you "should" have had 1 assist based on the quality of chances provided.
Who has the highest xA in history?
Since detailed tracking began (~2014), Lionel Messi, Kevin De Bruyne, and Thomas Müller consistently hold the highest season averages in Europe's top 5 leagues.
Is xA useful for goalkeepers?
Rarely. However, modern keepers like Ederson or Alisson who play long accurate passes can accumulate small amounts of xA over a season, which is unusual and valuable for their position.
How does "Game State" affect xA?
Leading teams often sit back, reducing their xA accumulation. Trailing teams push forward, often inflating their xA stats late in games. Context is vital when analyzing the numbers.
What is "Open Play xA" vs "Set Piece xA"?
set-piece xA comes from corners and free-kicks. Some players (like James Ward-Prowse) have massive xA totals dominated by set-pieces. Open Play xA is often considered a purer measure of creative ability in the flow of a match.

Real-World Examples
Case Study A: The "Unlucky" Creator
Player A has 12.0 xA over a season but only 4 Assists.
Conclusion: Player A is doing an incredible job. The strikers are failing. Do NOT drop Player A; consider replacing the forwards.
Case Study B: The "Over-performing" Creator
Player B has 2.0 xA but 8 Assists.
Conclusion: Player B is feeding elite finishers who are scoring from difficult positions (e.g., Son Heung-min). Player B's assist numbers are likely to drop (regress) next season unless chance quality improves.
