Expected assists (xA) is one of the most valuable metrics in soccer betting. While many bettors focus on goals and wins, xA provides deeper insights. It measures the quality of chances a player creates, not just the assists they record. This means you can spot hidden trends and gain an edge in the betting market.
What Is Expected Assists (xA)?
Expected assists (xA) quantifies the likelihood of a pass leading to a goal. Unlike traditional assist stats, which only count successful assists, xA evaluates the quality of the chance created.How Is xA Calculated?
The xA metric assigns a probability score to each pass based on:- The location of the pass.
- The positioning of teammates.
- The angle and difficulty of the chance.
- Historical data of similar situations.
Why xA Matters in Soccer Betting
Many bettors rely on outdated stats like assists and key passes. However, xA offers a better prediction of future performances. Here’s why it matters:1. Assists Can Be Misleading
Traditional assists depend on teammates finishing their chances. A creative player might produce many great passes, but if teammates fail to convert, their assist numbers remain low. xA removes this randomness.2. Identifies Underrated Players
Some players consistently create high-quality chances but don’t get credit. Betting on these underrated playmakers before the market catches on can be profitable.3. Helps Predict Future Form
If a player has a high xA but few assists, they are due for a breakthrough. Conversely, a player with many assists but low xA may not sustain their form. Recognizing these patterns helps in long-term betting.How to Use xA in Betting
Now that you understand xA, let’s explore how to apply it in soccer betting.1. Betting on Player Assists
Bookmakers set odds for player assists based on past numbers. If a player has high xA but low assists, they could be undervalued. Betting on them to register an assist can be a great opportunity. Example: A midfielder has an xA of 0.40 per game but only 2 assists in 15 matches. This suggests he is creating chances, but teammates are underperforming. Once his teammates improve, his assist numbers should rise.2. Finding Value in Team Bets
xA also applies to teams. A club with a high xA but few goals suggests attacking potential. Betting on them to score more in upcoming matches can be profitable. Example: A team has a total xA of 2.0 per match but averages only 1 goal. This means they are creating chances but struggling with finishing. If they start converting chances, betting on their goals market offers value.3. Live Betting Insights
xA updates in real time. If a team or player is generating high xA during a game but hasn’t scored or assisted yet, it could be a great in-play betting opportunity. Example: A team has an xA of 1.5 at halftime but is still scoreless. Betting on them to score in the second half makes sense based on their attacking performance.4. Spotting Overrated Players
Some players record many assists due to lucky finishes by teammates. If their xA is low despite a high assist count, they might be overperforming. Betting against them in assist markets can be a smart move. Example: A winger has 10 assists but an xA of only 3.5. This suggests his assists come from exceptional finishing by teammates, not consistent creativity. His assist numbers could decline soon.Where to Find xA Data
