I take it, that you weren't aware of our recent -hugely successful- preseason tour of Asia. Sold out stadiums in Jakarta(pulled in a much larger crowd than even Arsenal Managed to), Thailand, Australia ( sold out a full capacity of 95000 in less than 25mins!).
We have a huge fanbase in Asia. Chelsea has a large following in Africa, down to the fact that you've had some big African names in your squad over the years. But it's not particularly the most attractive for PR or Marketing though. Arsenal And Us have the stronghold in Asia along with ManU.
