Don't know much about him, but heard he is quite a big name over in Korea, had a few injuries that have set him back. Love his nick name, good stuff! Heard he is going to sign next week (19th), but you never know with Boro until they anounce it. Might have trouble getting fit if the korea season ended in November, might need a few weeks to get ready maybe. Hope this is true as he has a good reputation of being a talented player.
Hope it's true as well, he's had too much misfortune throughout this career and he deserves a chance to shine even brighter. He is currently the top scorer in the National Team as well. And yes, he'll need some time to get back into fitness as he has recently recovered from injury to his knee.
Here's a good thread about him from the FMTTM board. He goes by "Lee", rather than Dong or Gook. BTW...I'm a Boro fan and do a general footy podcast, but tend to talk about the Boro more than normal because of my support. Check it out at http://soccershout.com
He will no longer play in Middlesbrough it mentions it during the last sentences in the article http://news.bbc.co.uk/sport2/hi/football/teams/m/middlesbrough/7398544.stm
He should never have come to the prem league, totally outclassed, one of the worst players we have seen in a boro shirt. Good luck Gook, hope you find your level
