In England - Chester, the closest club to where I grew up, and despite once being a proud league club they seem to love struggling even more than Latics.
Germany - Frankfurt and Wiesbaden, as I've been over to watch their games.
Since living in Japan I've moved around a lot so picked up a few sides to look out for...
Suzuka Unlimited, closest team to where the wife comes from.
Nara Club, the closest team to me at the moment so watch them a lot with a number of other English guys.
FC Osaka, a team that might be relocating about 10 minutes from where I live now.
Kyoto Sanga, a Japanese friend supports them and I found out they are the only 'biggish' team in my region that didn't used to be the company team of a huge Japanese multinational corporation. A rare 'proper' football club with a long history.
