... Re loans, (in general now) i'm not convinced either way tbh. They certainly Do count towards HG, IF the player is loaned within the same association or country (including scotland for the FA). Although that actually likely has nothing to do with the registration of the player, but with the fact they are still spending 3 years as HG. whether that then still counts as club trained, i dont know.
Roberts counted as home grown, after his celtic spell. And (for whoever brought it up) Denayer i believe does as well. With us he would never have needed to be listed as HG, as he was U21, but i remember when Arsenal were interested in him all the reports claimed they were getting a home grown defender.
As for players loaned out to other leagues, i guess they dont count. I can see the logic in the fifa 'one registration arguement'. but i also am not sure how it works in reality, i.e if we loan a player out, but are paying his wages, do we de-register him, and then re-register when the loan ends? it makes sense to me that the player is on the books of the club, just like a secondment. but il be honest, im no clearer on it either way, and clearly, many on here interpret it different.
What we Have also categorically established (hey two out of three isnt bad) is that Angelino (all relevant to this thread) definately IS both HG and CT either way, due to his amalgamated stop time, irrespective of any loans.
