I absolutely agree with this, but I need to keep reminding myself that we are talking about just 4 out of 6 losses this season. It's all a learning curve and this is where our ability to change our first XI would make a big difference. Buying someone like Moura does exactly that. Every team has a couple of bad games in a season. Emirates Marketing Project have had it, Liverpool have had it and Man United have had it.
I'm in agreement with
@Raziel that Chelsea have a better squad than us. Not first XI but squad. What they don't have at this moment in time is a first XI that picks itself. They had that last season, but because of players going off form, Conte being strange and a departure of their star striker, they've not been able to replicate. This is the first season under Poch where I think injuries have played a detrimental effect on our season. Not having players like Toby, Wanyama, Dembele or them struggling to be fully fit hits us as it would any team.
