Unfortunately I fear James' knees won't be able to cope with the wingback demands now (maybe once in a while, but not consistently) and I'm not particularly convinced Gusto can give us an attacking output that we'd need in that position (maybe as a backup).
Hato would for sure be better as a LCB in a back 3, probably also a back 4 tbh (two left footers can work there if we do the back 3 in possesion thing Maresca did) so recruitment needed there for sure.
Quenda could do really well there. I know there were the rumours he avoided United/Amorim because of that, but Amorim uses his wingbacks really conservatively whereas Alonso feeds them really well, Frimpong and Grimaldo were genuinely amazing under him, so that may be able to convince him.
