Real Sociedad has announced that Isak will extend his contract with the club until 2029, ensuring his future at the La Liga side.
The Swedish striker's current deal expires in June 2026, but the club have decided to keep him on board for another four years.
The move is a significant coup for the Basque side, who have been linked with several high-profile players this summer.
Isak made a strong impression during his debut season at the San Mames Stadium, scoring 18 goals and providing eight assists in all competitions.
He was also named as the club's player of the year, demonstrating the impact he had on their campaign.
With the arrival of new manager Arteta and a strong squad, it seems likely that Isak will continue to be a key player for Real Sociedad in the coming seasons.
The fact that the club has chosen to extend his contract shows how much they value his contributions to the team, and it is clear that he will be an important part of their plans for the future.
Overall, Isak's extension is a positive development for both the player and the club, and it suggests that Real Sociedad are committed to building a successful team going forward.
