The interesting thing in Asia is that there are no in-built loyalties (born in a town, live in an area etc) so kids will either pick up loyalties from their parents maybe, or support teams that are doing well at the time they start following the Premier League. This means that there are opportunities for teams like Leicester if they can keep progressing and come on tours out here. Man City and Chelsea were in a similar position not so long ago and now they have a significant following. Of course United and Liverpool wont be caught unless they have prolonged periods of being really crxp but they have excellent marketing ability (Man Utd even have a tyre sponsor in each country etc). Newcastle and, to a lesser extent Sunderland fail, because everybody who saw them winning something, will be dead now! Lack of coverage of games is not an issue - I can watch almost all of them live, or delayed here.
The other thing with the no loyalty is that they do change the teams they support every season. If Chelsea are doing good, they support them.. can guarantee there are a fair few of them swapping from Chelsea to the Utd's, City's and maybe even the Leicester. Because alot of them havent been to the UK, or been to a match, there is no real loyalty. But Barca and Real are defo huge there aswell.
