Newcastle United have agreed to sign striker Alexander Isak from Real Sociedad for €70 million including €5m in add-ons.

Isak joined Sociedad in the summer of 2019 from Borussia Dortmund for €10m and, after spending four years at the club, becomes Sociedad's most expensive departure of all time.

Isak is set to become Newcastle's fifth arrival this summer, with Matt Targett, Nick Pope, Sven Botman and Charlie McArthur also moving to St James' Park.
