I'd like us to at minimum to offload Elneny, Mkhi, Soares, Luiz, Sokratis, Lacazette, Xhaka. Fear Torriera, Aubamayeng will be likely outbounds too. I wouldn't expect Mustafi, Kolasinac, or Özil to add into that. I would loan out Mavropanos, Chambers, Maitland-Niles, possibly Willock too. Barring Chambers none of the others would go at appropriate value.
So that's 1 fullback, 2 centre backs, 3 midfielders, 3 forwards. Crazy.
I'd embolden youth players such as Saliba, Nelson, Guendouzi, Nketiah, and Martinelli.
That may look some like this:
------------------------Leno/Martinez-----------------
Bellerin---Holding/Mustafi---Saliba/Medley--Tierney/Kolasinac
----------------------X---------Guendouzi---------------------
------------------------Smith-Rowe/Özil/Saka-------------------
-Pépé/Martinelli-------------Nketiah/Martinelli-----Saka/Nelson
Based on that we would need a quality starting forward, central defender and central midfielder. A whole new spine. A dependable right back.
I can see why we may end up holding on to Lacazette, Luiz, Soares.
So gutting. Arteta might be asked to make do like Lampard was(Pulisic,Girioud aside). I can't believe he was able to help Chelsea make Champions league with little inbounds, and can splash away this season.
