Lee Chung-yong has committed his long-term future to Bolton to end speculation linking him with a move to a rival Premier League club.
The South Korea international has signed a contract extension until 2013.
Lee, 24, has been in sparkling form for Bolton, who are lying fifth in the table going into the Premier League match against Blackpool on Saturday.
Bolton manager Owen Coyle said: "We have signed Lee on a contract extension. It is great news for the club that such a talented player will be here for a long time."
Lee follows in the footsteps of team-mates Fabrice Muamba, Stuart Holden and Danny Ward in signing a contract extension at the Reebok Stadium.
