Ali Al Habsi hopes to repay manager Roberto Martinez after completing a permanent move to Wigan.
Skysports.com reported on Monday that Bolton had accepted a £4million bid and Wigan later announced that the 29-year-old goalkeeper had joined them on a four-year deal.
The Oman international already feels at home at the DW Stadium having spent last season on loan there, being named Wigan's player of the year.
After being second-choice throughout his four years at Bolton, Al Habsi finished with 34 league games as the Latics survived on the final day.
"I want to say thanks to the gaffer for being confident to bring me to this football club," he told Sky Sports News.
"It's like my club now. I was here last season and really enjoyed myself.
"To come from Bolton on a season-long loan and get player of the year was great, especially when it was my first time as a professional to play week after week.
"I come here with 100 per cent focus and to give everything for this club.
"Everyone was maybe excited by the performances I showed and I hope to give more to the gaffer for keeping me at this club.
"I am so grateful that the gaffer gave me the chance to prove what I can do and now I want to repay him, and the Wigan fans, for making me so welcome last season."
Al Habsi joined Bolton in 2006 but mainly provided cover to Jussi Jaaskelainen.
Good deal for all
And although he was handed just 10 league appearances for the Trotters, he praised everyone at the club after completing his permanent move to Wigan.
"I want to say thanks to (manager) Owen Coyle, (chairman) Kevin Garside, even the Bolton fans, for all the four years I was there and the professional way they sold me," he added.
"We came to a point where everyone is happy - Bolton is happy, Wigan is happy. The deal is great for both clubs."
