Newcastle United have reportedly warned striker Alexander Isak that he must return to full training with the club if no acceptable transfer offer arrives in the coming weeks.
The Sweden international has been absent from pre-season preparations with what was officially described as a thigh injury, but he is currently training separately from the main squad at the request of manager Eddie Howe.

The Newcastle boss is understood to be concerned that Isak’s current stance could negatively affect team morale.
According to multiple reports, club officials have informed the 24-year-old that he will not be sold this summer unless Newcastle receive what they consider an acceptable bid.
The Magpies have already rejected a £110 million ($147.8 million) offer from Liverpool, holding firm on their £150 million valuation of the player.

Isak is thought to be disappointed with Newcastle’s stance
While sources suggest the “exit door is not closed,” Newcastle are making it clear that Isak is expected to remain professional and prepare to rejoin the squad if no improved bid arrives. With his contract running until 2028, the club faces little pressure to agree to a deal this transfer window.
Reports claim Isak is pushing for a record-breaking move to Liverpool and has shown “no interest” in playing for Newcastle again. However, Howe has insisted there is still a way back for the forward, expressing optimism about his potential reintegration into the team.

Isak is expected to miss Newcastle’s Premier League opener against Aston Villa this Saturday, with the club’s second league match — a home fixture against Liverpool on August 25 — adding further intrigue to the transfer saga.
