After 7 games last season it was remarkably similar, which is why it doesn't really seem sensible to look into this too much yet.
It's encouraging, that's about it.
I do suspect that we'll end up better off on this metric than last season as our xG exploits in the early part of the season were quite James-centric I seem to remember, and they tailed off a lot over the course of the rest of the season. I *think* the current set-up is a little bit more sustainable than the "give it to James" tactics we employed for the same period last season, but you never know.
