In reply to your eloquently put (as ever) compiled list of signings, squire;

a) Diego Carlos decent
Certainly looked like an upgrade
b) Augustinsson why ?
Have you seen Digne lately?
c) Coutinho there is a player in there but Gerrard & his 10 coaching staff cannot get a tune out of him
Window dressing. One for the youngsters to cream over.
d) Lucas Digne is he a significant upgrade on Target NOT @ £26 million
He is, Target was that poor and lightweight.
e) Calum Chambers decent acquisition far more assertive the Ezri Konsa
Agreed
f) Robin Olsen good backup goalkeeper
Agreed
g) Boubacar Kamara good signing but struggling to paper over the cracks
Top draw player. Unfortunately, due to his cohorts, he’s resigned to playing a giant game of ‘Whack-A-Mole’.
