It’s reductive to say the differences season to season are down to a single player. We have a different back four, more rotation, a World Cup in winter, different style of play (not just down to Haaland but a lack of pace on the wings), and we’ve lost players too.
We could just as easily put the stats down to “losing Zinchenko” (another reductive and wrong argument).
The fact we have scored the same number of goals as last season at this point means nothing. Yes it shows a higher reliance on Haaland that they’re all through him, but has anyone looked at chance creation stats? I’d assume we are more lethal with chances going through him so maybe that means fewer created chances. Foden has dropped off but at the start of the season he was scoring too, so that could be a reason. Mahrez has started scoring again so that could help. Grealish not yet fully off the ground
