I think this is the big issue with the January window in general. It's ok having the window open, but how many teams are willing to part with their best players midway through the season? It seems to be less and less each year.
It's frustrating because Carlo and co must see our weaknesses, but he knows it has to wait until Summer. It doesn't help that the 2 midfielders that he can trust are both out. Games are won and lost in midfield and without Allan and Doucoure, ours is a gaping hole that allows anyone to run through it.
TLDR: Our midfield is Katie Price.
