Sunderland boss Steve Bruce is confident new signing Ji Dong-won can cut it in the Premier League.
Ji finally put pen to paper after having to wait for the administrative details of his move, including a work permit, to be finalised.
Bruce said: "The boy has been in fantastic form for both club and country and he was one of South Korea's stand-out performers at the Asian Cup, so we are delighted to bring him to Sunderland.
"The Barclays Premier League is very different to the K-League, so there is hard work ahead, but you just have to look at players like Park Ji-Sung and Lee Chung-Yong to see how well Korean players are adapting to its pace and physicality."
