Break it down
Same concept, sharper angles — read it like a scout, not a textbook.
The idea
Expected goals (xG) estimates how likely a shot is to become a goal based on shot quality.
In plain terms
A 0.4 xG chance means that type of shot goes in about 40% of the time on average.
Why top teams use it
It helps coaches and analysts judge chance quality rather than just counting goals or shots.
Who shows it
Used across Premier League broadcasts, Opta, StatsBomb, and club analysis departments.
Spot it live
Whether a team is creating high-xG chances or just taking lots of low-quality shots.
