Yeah footystats seems to have different ones, but I think even there the point is clear - xG for West Brom of 1.76 and yet they scored 0, so clearly on the (admittedly flawed but still helpful) xG measure, our defence was not that great…
We've had a lot of the ball but all the better chances are from free kicks around their box - a bit of a battle as opposed to a "classic".
