BORUSSIA DORTMUND HAVE completed the €10 million signing of Swedish prodigy Alexander Isak from AIK.

Isak — already a Swedish international and a player who is often compared to Zlatan Ibrahimovic — had been heavily linked with Real Madrid, though appears to have opted to join the Bundesliga side instead.

“Borussia Dortmund have signed talented young Swedish striker Alexander Isak,” read the club’s statement.

“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 made his international debut earlier this month against Ivory Coast.

He then became youngest goalscorer in Sweden’s history in his second cap netting against Slovakia.

Dortmund sporting director Michael Zorc hailed the signing, revealing his side had beaten some of Europe’s biggest clubs to Isak’s signature.

“Alexander Isak is a hugely talented striker, who many top clubs in Europe wanted to sign,” said Zorc.

“We are delighted that he has chosen Borussia Dortmund. Both BVB and the player himself are convinced that this transfer has great potential.”

Isak only made his professional debut under a year ago, scoring for AIK against Tenhults IF at the age of 16 last February.
