Yeah. There's no denying that we are a different force going forward. I have no long term worries about xG, as i trust any of our forward line to create & convert chances at expected rates.
There are concerns. At the back when defending set-pieces and the red cards. If it were just these 2 reds (and goals conceded as well actually) i wouldn't be too concerned. But how many times can a freak occurance happen before it stops being a freak occurance? And both these flaws have followed him around.
I'm happy. But there is still a whiff of "martinez' attacking football after the pragmatic Moyes" about it. (and, before the usual suspects appear. I know Moyes played good football quite a bit towards the end there. I also know that the grass wasn't greener with Koeman)
Think xg concerns covers goals expected from chances created vs goals conceded from chances allowed.
Best teams have a nice healthy inverse relationship creating lots and allowing few, while teams like us are mooching about in the middle somewhere allowing too much and not creating a lot.
