Arsenal are in talks with agents for Real Sociedad striker Alexander Isak.

Sport says any potential deal would require Isak's club Real Sociedad waiving the 22-year-old's exorbitant £76million release clause.

The Gunners are desperately seeking more reinforcements up front after cutting ties with Pierre-Emerick Aubameyang, who joined Barcelona last month.

The north London club were frustrated after being beaten to the signature of Dusan Vlahovic, who joined Juventus from Fiorentina.

Alexandre Lacazette and Eddie Nketiah are out of contract at the end of the season and several names are said to be on Mikel Arteta's striker shortlist, with Isak near the top.

But the Gunners believe Isak's release clause to be an 'out-of-market price' that must be lowered in order to do a deal.
