Bolton Wanderers have confirmed on their official website that playmaker Lee Chung-Yong has left the club in order to join Crystal Palace tonight.
The South Korean international, 26, was scheduled to be out of contract at the end of this season, meaning the Trotters were vulnerable to losing the midfielder.
With three goals and three assists this season, Lee has impressed this season, and it's little surprise to see him return to the Premier League.
Bolton have confirmed that Lee has moved on to Selhurst Park, with Barry Bannan heading to the Macron Stadium in part exchange.
Palace have also announced that Lee has signed a contract until 2018, meaning it's a three-and-a-half year deal for the midfielder after completing a late deadline day transfer.
With pace down the flanks in Yannick Bolasie and Wilfried Zaha, adding Lee into the mix is a superb acquisition for manager Alan Pardew, with Lee able to unpick defence with skill rather than speed.
That balance will be valuable in the coming months as the Eagles look to survive in the Premier League, and Lee becomes Palace's sixth signing of the transfer window.
Lee joins Yaya Sanogo, Jordon Mutch, Shola Ameobi, Pape Souare and Zaha in making moves to the South London club as Pardew's revolution continues.
