I’m another one who doesn’t get this xG business - I know others understand how it’s calculated better, but yesterday’s game exposes how a lot of it is BS for me. Apparently our xG was 1.87, in a match where we dominated from start to finish, scored 3 goals that all came from shots no more than 10 yards from goal, as well as hitting post, bar and their keeper making a number of tough saves. How does that equal us ‘deserving’ to score less than 2 goals?
I worked out early on that I had zero need to know what xG means. I've been much happier ever since.
No, 1.87 was the xG for our whole performance - that just sounds like bullshit to me considering how the goals were scored. It’s not like any of our goals came as a result of a speculative shot from 30 yards that go in 1 time in a 100. Thinking more about it, the other misleading bit about xG for me is does it take into account the game situation? If you are 2-0 up and coasting to an easy victory off the back of a couple of early goals I could easily see a situation where your xG would be lower than for a team chasing a game or desperately seeking a late winner. XG stats would indicate the latter were a more deserving winner, even though it’s clearly not the case and would explain why our xG was lower than expected recently - in pretty much all of our recent run (Leicester aside) we have been under little pressure to go chasing more goals and controlled the games.
