I think if December goes as well as we all think/hope it will then we won't need to change anything.
The squad has proved that they can cover injuries to apparently indespensible players in both midfield and in front. 4 from 4 doesn't lie.
We have depth at the back too which I believe could cover anything but the most unforseen injury crisis.
We have plyers coming back whilst some teams are losing them. Not a bad place to be.
