Alexander Isak has been training alone at Real Sociedad with his future at Newcastle still up in the air.
Isak did not travel to Singapore with his Newcastle team-mates for their pre-season tour, with the club noting that he would be absent due to suffering with a ‘minor thigh injury’.
Instead, the 25-year-old has been undergoing individual training at the Basque club where he made more than 100 appearances in all competitions between 2019 and 2022.
Mail Sport understands that Newcastle are yet to confirm whether they are aware of Isak returning to Sociedad to continue rehabilitation for his injury.
Isak remains a top target for Premier League champions Liverpool, with Arne Slot’s side linked with a £150million move for the striker.
There had also been interest from the Saudi Pro League in signing Isak – who has netted 54 Premier League goals since joining the Magpies in 2022 – but he is understood to be intent on remaining in Europe.
