Could TFC do the following :
Go around to countries like Greece, Colombia, Mali, Cameroon etc. Sign top U21 players to the academy and 'trial' them. Then who they like they can bring up to the senior team as 'homegrown' and not count towards cap hit.
You really wouldn't have to do all that much scouting if you went with quantity over quality for trialists, question is : would any transfer fee hit our cap and what do we need to make someone 'homegrown?'
