FC Seoul have strengthened their squad with the signings of midfielder Server Djeparov and winger Choi Tae-wook.
Djeparov, the 2008 AFC Player of the Year, joins on a six-month loan from Uzbekistan powerhouse Bunyodkor, whom he helped to the semi-finals of the Asian Champions League two years ago.
"I have wanted to play in the K-League for a long time and it's an honour to play for FC Seoul, who are one of the best teams in Korea,'' the 27-year-old midfielder told the club's official website.
"I saw Seoul's matches in last year's AFC Champions League. Though they failed to reach the last-four stage, they were very impressive.
"I want to be a player who can help the team. I will do my best and try to show beautiful football. I hope the fans here will support me.''
The capture is a coup for the K-League club given Djeparov, the Uzbekistan captain, is one of the more highly-regarded midfielders in Asia.
Choi, meanwhile, arrives from Jeonbuk Motors on a three-and-a-half-year contract.
The former South Korea international was instrumental as Jeonbuk lifted their first K-League title last year and has also helped the Jeonju-based club to the quarter-finals of this season's Asian Champions League.
The 29-year-old boasts a record of 29 goals in 245 games in the K-League and enjoyed a fine season last term with nine goals and 12 assists.
Seoul, who currently lie third in the table, will be Choi's fifth K-League club after Anyang Cheetahs, Incheon United, Pohang Steelers and Jeonbuk. He also enjoyed a stint in the J.League with Shimizu S-Pulse.
Choi, who has played 29 times for the national team, is expected to be ready to face K-League leaders Jeju United on Saturday at Seoul World Cup Stadium.
