I think it's 'home-grown' players. But either way, we've still got Carrick, Hargreaves, Brown, Ferdinand, Rooney, Welbeck etc. We're a lot better equipped to deal with this rue than the rest of the top teams in EnglandArsenal will be screwed but so would we. My understanding is that the six players would have to be english players. Therefore, players like Ryan Giggs, Darren Fletcher, John O'Shea, Jonny evans, darren gibson etc would be classed as foreign because they play for other "countries" (i.e. Wales, Scotland, Northern Ireland) and Republic of Ireland.
Effective rotation would become very difficult because the english players would need to play almost all the matches.
