What is Expected Goals?
Expected goals is simply a measurement of the quality of scoring chances in the football game. When a team creates scoring chances in football, it’s analysed and presented as an XG figure. If any scoring chance was a golden opportunity and would be scored, it receives a higher expected goal figure.
For example, if the goal-scoring opportunity had a 90% chance of being scored, the XG would be presented as 0.8. And if an opportunity to score was more than speculative, it would receive a lower expected goal figure. If a goal opportunity had a 20% chance of being scored, the XG goals would be presented as 0.2. This is a perfect example of a lower XG football stats figure.

Reasons Why Expected Goals Are Important
XG can be beneficial since they increase the sample sizes used when analysing football matches. Football is a low-scoring game, and in most cases, scoring goals is rare. And as a result of this, the data of pure goals can be misleading. There’re many examples each season where a football team that created more scoring chances ultimately lost the game.
Basic goal data, in most cases, has trouble reflecting this and can be unrepresentative of the real game results. XG takes all the chances available into consideration by calculating the total number of goals that are scored from every position.
Before the expected goals, metrics such as the number of shots were used to analyse games. Similar to goals, these statistics can prove to be misleading. There are some cases where the shots per 90 minutes are the same for the two teams in the same match. In this case, the shots data would place the teams in the same category, but the expected goals can help separate the two.
Another reason why XG is important is that it can help you increase your chances of placing winning bets. This is because you can make informed decisions from the data or information available.
