The expected goals (or xG) stat certainly isn’t everyone’s cup of tea.Whenever Brendan Rodgers’ Celtic are in televised action, you’re likely to see the side’s expected goals stat next to their possession, shots on target, et cetera.

The term refers to a new stat in football which rates chances from 0 to 1 depending on how likely they are to result in a goal.Despite initially being used only in data analysis circles, xG stats are now widely seen in mainstream football coverage.For some, they’re insightful.

For others, they’re nonsense.
