So we're underperforming our xG by 1.39xG
Against Brentford we notched 3.89xG and scored 3 goals.
So 0.89 of that 1.39 underperformance was from one game when it didn't matter to the result.
The remaining games we are underperforming our xG by a grand total of 0.4xG. So not even half a goal.
If we'd matched our xG exactly we'd have practically the same level of points we do right now. I hardly think that's evidence our forwards are killing us.
