So looking at the "matchday squad", this was our bench against Brentford:
Hoever
Marcal
Jordao - loaned out
Trincao - will be in starting 11
Chiquinho
Ruddy
Giles - being loaned out today
Traore - Sold
Cundle
Raul will be back in the 11 so Fabio will replace Trincao's space on the bench. Saiss will be back, So Toti will drop to the bench in place of Jordao's spot. Donk will be back in his standard role of bench warmer so takes Adama's place. So we're left with one space left to find a player (assuming Giles goes), which will probably be a young name until one of Neto, Jonny or Boly are fit and able to return.
So very soon we'll likely see the following:
Sa
Semedo Kilman Coady Saiss RAN
Moutinho Neves
Trincao Jimenez Podence
Subs: Ruddy, Hoever, Marcal, Toti, Chiquinho, Cundle, Donk, Fabio + 1 more.
If anything, we look light in the wide attacking areas until Neto gets back.
Edit: I totally forgot about Hwang, who will probably take the final spot on the bench and covers a wide area.
