### 🎯 What is Expected Goals (xG)?

Expected Goals (xG) is an advanced metric that quantifies the quality of a scoring chance by evaluating multiple factors including shot location, angle, type of assist, and defensive pressure.

**How xG relates to our data:**

* Based on historical [match statistics](https://docs.sportmonks.com/v3/tutorials-and-guides/tutorials/statistics/fixture-statistics) and shot outcomes
* Correlates with [team](https://docs.sportmonks.com/v3/tutorials-and-guides/tutorials/statistics/team-statistics) and [player performance](https://docs.sportmonks.com/v3/tutorials-and-guides/tutorials/statistics/players-statistics) metrics
* Powers [prediction models](https://docs.sportmonks.com/v3/tutorials-and-guides/tutorials/odds-and-predictions/predictions) and analysis

💡 **Use case:** Identify teams/players that are underperforming or overperforming relative to the quality of chances they create.

These are the topics we will cover:

{% hint style="info" %}
Please note that the availability of xG values varies depending on the package you choose. 

* The **Basic** package offers access straight after the match has finished to all xG statistics.
* The **Advanced** package offers real-time availability to all xG statistics.

You can find more information on our dedicated [pricing page](https://www.sportmonks.com/football-api/plans-pricing).
