Home advantage in expected goals
Why every match on this site has a Home xG and an Away xG.
Home teams tend to create more and concede less. That is the home edge in one sentence, and it is why every match on this site has two numbers, not one.
Two numbers, one match
Home xG is the goals we would expect the home team to score in this match. Away xG is the same for the away team. Together they make up Match xG.
That is all. The numbers are there to help you see a match more clearly, not to tell you what to do.
