It is reported that Isak is working regularly at Real Sociedad's facilities in Zubieta, accompanied by a personal fitness trainer. Medical tests have revealed no injuries, leading some to suspect that he may be using a "strategic injury" to avoid public exposure before a potential transfer.

Newcastle initially stated that Isak would miss their tour with a "minor" thigh injury, but later revealed that he had made a transfer request. This has fueled interest from other clubs, including Liverpool and Al-Hilal from the Saudi Pro League.
