Ki Sung-Yueng has joined Swansea after the English Premier League club agreed to pay Scottish champion Celtic an undisclosed club-record fee for the Korea Republic midfielder.
Ki has agreed a three-year contract and will now wait for a work permit and international clearance before officially joining up with his new teammates at the Liberty Stadium.
The 23-year-old, reported to have cost £6 million ($9.2 million), won't be available for Saturday's match against West Ham United and he admits he can't wait to eventually get his first taste of Premier League action after watching the English top-flight as a young boy.
"This is something I have dreamed about since I was a child - playing in the Premier League against the best players in the world. I can't wait to play my first game," Ki told Swansea's website.
Ki, who helped South Korea win the bronze medal at the recent London Olympics, believes Swansea's passing style makes the Welsh club an ideal team to showcase his talents.
The presence of former Barcelona and Real Madrid star Michael Laudrup as Swansea manager also played a part in persuading him to leave Celtic.
"When I look at Swansea I see a club that is growing and growing, and the style here is very attractive to me," Ki said.
"Last year I watched them a lot in the Premier League and they did things very differently to a lot of the other teams. They wanted to keep the ball and pass it around, which I love to do. When they didn't have the ball they worked so hard to get it back quickly.
"It was very impressive, and I think I can grow as a player here and help the club move forward.
"The manager is another big attraction. I remember watching him when I was younger and I was amazed by how good he was.
"Now I want to learn from him in order to help me become a better player. I learned a lot at Celtic - it helped me become more of an all-round player."
