Sunderland have completed the signing of South Korea international striker Ji Dong-won on a three-year deal for an undisclosed fee from Chunnam Dragons.
The 20-year-old is regarded as one of the most promising players in Asian football and had attracted the interest from a number of clubs throughout Europe.
But it is the Black Cats who have completed another transfer swoop to follow hot on the heels of the arrival of teenage forward Connor Wickham from Ipswich on Wednesday.
The forward, who stands 6ft 2in tall, bagged four goals at the recent Asian Cup and has six goals from 11 appearances overall for his country.
Stadium of Light boss Steve Bruce believes that Ji will be another excellent addition to his squad but admits he may need some time to adapt to the rigours of Premier League football.
Bruce said: "The boy has been in fantastic form for both club and country as he was one of South Korea's stand-out performers at the Asian Cup, so we are delighted to bring him to Sunderland.
"The 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 Park and Lee Chung-yong to see how well Korean players are adapting to its pace and physicality."
