Interesting article on Park, I never knew he was dropped by South Korea but he also seems to have vanished and hasn't been answering any calls etc. http://bleacherreport.com/articles/1189395-arsenal-the-curious-case-of-park-chu-young-grows-even-stranger I do think that he has the quality to succeed in the Premier League, but this player has been a mystery for the whole season.
He's probably reached a stage of depression after Wenger ruined his career to the point that he's been dropped by Korea - he was their star player till we got hold of him. I feel very sorry for him.
