Fair enough. I'm surprised that Kane would be negative (even if that includes free kicks) but if these figures are accurate (xG is a moving stat that can be calculated in many ways) then that is a huge difference.Son's goals above xG since the start of last season is +8.6
Kane's goals above xG since the start of last season is -2.5,
That's an 11 goal difference. It's not even close.
