They can change - with permission from the PL.
The PL will not give them permission to totally re-jig the numbers, but if they loan out a player and bring in someone already on their books not previously nominated, then it'll be ok.
Yes - I'm sure it is submitted today.
Yes - I'm sure the PL will publish all the squads on Sept 1st when they are finalised.
I am not sure if the albion will announce the initial squad they submitted today - but we'll know 18 of them tomorrow for sure.
Yes, but only if all over 21 aged players not in the squad have been got off the books - ie Towell, Norwood, Normann, Barclay and the injured Ahannach.
I expect Suttner or Schelotto not to be named in the 25 man squad and sold or loaned to Europe before the end of August.
I'm pretty certain we'll name a 24 man squad with 7 HGPs.
