They're worse away, but not doing well home either (well, they're doing really well on actual goals conceded, but their xG against being high suggests it's either their GK being good or opponents bad finishing that's the reason rather than a good defence).

Burnley has played at home one less time than some of the teams doing worse than them, so if you look at xG against per home game only West Ham and Nottingham Forest are worse in the league.
