I don't want to sound patronising here, genuinely just giving my take on XG as I know plenty of people don't really get it. But when your team creates chances and mainly controls the game, thats what good XG is. If you are under the cosh and basically getting dominated for the whole game. thats what bad XG is.
Under Lampard last season, our opponents were regularly getting twenty shots off against us (even chaff like Fulham and Southampton were having treble the chances we were) and we were barely surviving in games, mainly thanks to last ditch blocks from Coady and Tarkowski. We were clearly inferior to almost all opponents. That isn't the case any more. We're a stronger, more organised team this season, we've just been terrible at converting chances.
I'm honestly puzzled how people can't see the improvement compared to Lampards last few months.
