If I am not mistaken the current make up of the squad is as follows
PL
Home grown - 10
non home grown -15
CL
Club trained - 5
Assoc trained - 3
Group A - 19
With Winks and Reguilon the only ones looking close to leaving at the moment that would get club trained down to 4 and Group A down to 18 so if just those transfers happen one Group A player will not be registered and we have space for one Assoc trained player. If Sar and Gil (both count as u21 in PL) go as well we can get a Group A player and not worry about not registering anyone.
Edit - if Tanganga goes club trained goes to 3 and couldn't be replaced in CL squad other than by getting back another club trained player.
