A Guide to Expected Goals (xG) in Football Betting

Metrics are essential in sports betting, as they increase the probability of making well-informed decisions when placing bets. The wealth of information it provides, such as historical trends, point differentials, and player efficiency ratings, contributes to more accurate predictions, mitigating risks and increasing long-term success.

Expected goals (xG) is one of the most common statistics used in football betting. Its main benefit is that it provides a detailed measurement that aids in the calculation of team and player performance and understanding the effectiveness of their offensive and defensive strategies.

Like other metrics, expected goals can have limitations, but a complete understanding of this metric can help with clarity and approach to football betting decisions. The following guide explains everything you need to know about expected goals:

Understanding Expected Goals (xG)

xG is employed to evaluate the quality of scoring opportunities during a match, indicating the possibility that a given shot will result in a goal.

The metric is assessed based on a scale of zero to one, with zero representing an impossibility of scoring and one indicating an anticipated likelihood of scoring every time. Sports gamblers can use xG to identify teams with underrated offensive potential, thus improving their strategic approach in predicting match outcomes.

How xG Influences Football Betting

With its comprehensive and specific approach, xG can be beneficial for online soccer betting in Singapore and is considered a more objective method for football analysis than traditional statistics. Hence, bettors may enhance their understanding of a team’s offensive and defensive strengths and weaknesses. They can make more informed betting selections by considering xG based on several factors, including:

Shot Angle and Distance

In general, shots from central positions and closer distances to the goal yield higher xG values, reflecting their likelihood of resulting in a goal.

Shots at acute angles or from greater distances have lower xG values because they are statistically less likely to result in a successful scoring opportunity. In football analytics, such criteria help assess the quality of scoring opportunities.


Observe teams with a high expected goals but a lower actual goal count, as bookmakers might undervalue them.

For those seeking favourable odds, strategically placing stakes on teams regularly showcasing attacking ability, even if their goal conversion falls short, can be beneficial. Conversely, caution is needed when betting on teams relying on luck with a high goal count but a low xG since it may not be sustainable.

Shot Taken Using Head or Foot

The body part used for a shot, such as whether it was taken with the head or foot, is a crucial factor in xG football calculations. Since different body parts have distinct conversion rates, they affect the expected goal value.
