David Moberg Karlsson joins from IFK Goteborg.
Sunderland have signed Swedish winger David Moberg Karlsson from IFK Goteborg.
The 19-year-old, who can also play up front, has signed a four-year contract on Wearside and moves to the Stadium of Light for an undisclosed fee.
The forward began his career with IFK Mariestad before joining Goteborg in 2010, making his senior debut for the Allsvenskan club as a 17-year-old.
He made 28 appearances for Goteborg in all, including 10 during the current campaign.
Moberg Karlsson is a Swedish U19 international and was in action for his country against France earlier this month.
He played alongside former Black Cat Tobias Hysen with Goteborg and won the Swedish Cup last month, appearing as a substitute against Djurgardens IF in the final.
