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.
Coyle, who arrived in January from Burnley, believes the future is looking ever brighter at the club.
He said: "These extensions show we are looking to build a club. I am very forward thinking in trying to improve and help these young players on our journey.
"With the talent he has Lee is getting better day by day and I am thrilled he has signed up.
"What I am wary of is we do not burn him out as he has played two years without a break. He managed to have three weeks off after the World Cup that's all."
Lee, who arrived from FC Seoul last summer, has started all 14 league games this season and weighed in with two goals.
