Ian, Figgy - I'll do that and report my findings, once I get my lappy back from the mender's.
I'm still finding this hard to get my head around though

Notice that one of my issues that hasn't been picked up on is that I intend to retain Asian national players from non-playable leagues, eg Bhutan, Sri Lanka. I don't have the firepower to run a huge db; large is the best I can manage.
Just to answer one of your questions Ian, AFAIK there are very few non-Asian players in Asia,
prolly one or two in Hong Kong [note to self: remember to load patch to fix missing HK league in 5.0.3

], then there's Qatar. The league I do have some familiarity with is the NFL in India. They have a ruling max 4 foreigners in a squad/3 in match squad. The richer clubs do therefore have 3-4 foreigners, often Brazilians or Nigerians, but they are really pants players who are in India 'cos they ain't good enough for a league with a higher reputation. But let's not get confused here - I wouldn't be retaining foreign mercenaries playing in Qatar, only players with Asian nationality.
So, I'll give it a go. If the Malaysian league gets filled up with Bhutanese yak herders I'll realise the game is unbalanced
