Manchester City are reportedly considering a move for Real Sociedad striker Alexander Isak during this summer's transfer window.
The 21-year-old has been in impressive form for his Spanish club this season, scoring 12 times in 20 La Liga appearances, including nine goals in his last six outings in Spain's top flight.
According to The Mirror, Borussia Dortmund have an agreement in place allowing them to re-sign the Sweden international for £25m at the end of each season, but the attacker is not interested in returning to Germany.
The report claims that Man City boss Pep Guardiola is an admirer of Isak and could attempt to bring him to the Etihad Stadium ahead of the 2021-22 campaign.
The Citizens are expected to be in the market for at least one new striker this summer as the club's record goalscorer Sergio Aguero could potentially leave on a free transfer.
Isak featured twice against Manchester United in the last-32 stage of the Europa League but could not help his team overcome the Red Devils.
