Borussia Dortmund have completed the signing of AIK striker Alexander Isak, widely dubbed as 'the next Zlatan Ibrahimovic', on a "long-term deal".
The teenager is regarded as one of the most promising in Europe, having made his debut at AIK as a 16-year-old and quickly establishing himself in Rikard Norling's starting line-up.
Real Madrid were heavily linked with Isak, who reportedly shares an agent with Luka Modric, with a €10 million transfer being close to completion before Dortmund made their move.
"Alexander Isak is a hugely-talented striker, who many top clubs in Europe wanted to sign," sporting director Michael Zorc said in a statement.
"We are delighted that he has chosen Borussia Dortmund. Both BVB and the player himself are convinced that this transfer has great potential."
The club added: "Due to the fact that Isak is still a minor, the completion of the transfer still requires special approval by world football’s governing body FIFA, which all parties expect to receive very soon."
Isak, who turns 18 in September and has reportedly signed a contract until 2022, had 13 goals in 29 games for AIK this season and recently became Sweden's youngest ever goalscorer.
