I could be wrong and regularly am… but I think the u21 exemption thing only counts for ‘home growns’ not loans
I've just googled the rules and it doesn't say anything about loans plus he joined Brighton at the age of 18 so he's counted as a home grown player as he would have played in England 3 years by the time he turns 21
I said I could be wrong The rule I remembered is for the EFL where the rules are stricter. In the champ he would have counted towards our squad list. In the PL he doesn’t. Sorry for the confusion, good news if it leaves us a potential extra place (if we use it).
