I've updated this again and with no incoming business looking likely.
With Adama gone and Neto/Hwang not quite ready to return, we're quite light in those wider roles as it stands, but overall, it is probably the position with most depth and quality in the squad when they are all fit and healthy.
I imagine Jordao and Giles will go out on loan, leaving us with the following:
Sa, Kilman, Coady, Saiss, Semedo, Neves, Moutinho, Ait-Nouri, Trincao, Raul, Podence
Ruddy, Gomes, Hoever, Jonny, Dendoncker, Cundle, Neto, Hwang, Fabio
That leaves Boly, Mosquera, Marcal and Chiquinho out of the typical matchday squad. Boly is done, Mosquera I can't imagine really becoming a fixture for the remainder of the season, Marcal will inevitably get crocked again soon and Chiquinho will likely flit between the first team and the U23's.
