How does the xG chart work? I genuinely have no idea what it means
How long have you got?
xG is 'expected goals'
It's a stat that shows how many goals a team should be scoring (or conceding) based on the chances during a match.
For example, against West Brom, our xG was 1.73 and West Brom's xG was 1.52.
QPR v Boro was 1.51 v 2.07.
So at the moment our total xG in the league for the season is 3.80, however, we've only scored 3 goals so we are underperforming our xG.
There's all sorts of models out there that can calculate xG differently, but most will give very similar answers.
For example, a penalty is normally valued at 0.76 xG.
I find fbref.com a brilliant website that goes deep into stats, not just on teams, but individual players too.
Some players (such as Heung Min Son) make a mockery out of xG because his finishing is ridiculous, in fact one of the best. So if he's getting a chance calculated at say 0.76, the chances are (based on his history), he'll score more than 76 times out of 100 when faced with that opportunity.
