Sunderland have revealed that they have secured the services of Swedish youngster David Moberg Karlsson.
Reports emerged earlier today that the Black Cats have reached an agreement with the 19-year-old and his club IFK Goteborg over a move to the Stadium of Light.
The Premier League outfit have now confirmed that speculation by revealing that the attacker has signed a four-year contract.
Having made his debut at the age of 17, Moberg Karlsson went on to represent Goteborg on 28 occasions.
