Real Sociedad striker Alexander Isak has been seen in London amid interest from Arsenal.

The Gunners failed to secure the signing of top target Dusan Vlahovic after the Serb joined Juventus this week but the north London side are reportedly considering a move for Isak as an alternative.

The Sweden international has heightened speculation over a move to Arsenal after he was spotted in London this weekend.

A video has emerged on social media, which appears to be taken in Soho, that shows the 22-year-old with Real Sociedad team-mate Adnan Januzaj.

The former Manchester United winger also posted a photo with Isak to his Instagram story, writing: "My brotherrrrrrr @alex_isak."

An Arsenal fan account shared the photo on Twitter with the caption: "Januzaj and Isak in London together..."
