Chelsea are reportedly preparing to battle Liverpool and Arsenal for the signature of Real Sociedad forward Alexander Isak during this summer's transfer window.
The 21-year-old enjoyed a strong 2020-21 campaign at club level, finding the back of the net on 17 occasions in 34 La Liga appearances.
Isak has also made a positive impression in Sweden's opening two matches at Euro 2020, and both Liverpool and Arsenal have recently been credited with an interest in his services.
According to AS, Chelsea are also keen on the forward, who has a release clause of €70m (£60m) inserted into his current deal with Real Sociedad.
The report claims that the Blues view the Swede as an alternative to Borussia Dortmund's Erling Braut Haaland, who could ultimately be priced out of a summer move.
Isak found it difficult to make his mark at Dortmund after a switch from AIK in 2017, but he impressed during a loan spell at Willem II before joining Real Sociedad on a permanent deal.
