Seoul, South Korea. You're expected to do well, but there are a few problem areas in the squad and strengthening is needed. More of a challenge would be Jeju or Gangwon, currently they're second last and last respectively, and last year Jeju was last and Gangwon was third last.
Also, the Chile league was strangely fun to play in when I did a season there in Championship Manager 08, perhaps give that a go too. You have amazing players, and even the ones you don't play have loads of skill and get picked up by foreign clubs all the time. They're not necessarily EPL good (some of the players definitely are though) but good nonetheless.
