Alexander Isak faces key talks with Newcastle manager Eddie Howe following his return to Tyneside.
The 25-year-old Sweden striker returned to Tyneside at the weekend after spending some time on fitness training at his previous club Real Sociedad, while Premier League champions Liverpool formally expressed their interest in him with a £110million bid that was quickly rejected by the Magpies.
He arrived at the club's training complex on Monday morning as the rest of the players returned from a pre-season trip to Singapore and South Korea.
Isak missed the tour citing a hip injury amid intense speculation about his future.
Newcastle have repeatedly insisted they have no plans to sell their star striker, valued at around £150m, this summer.
However, his announcement that he would like to consider leaving St James' Park, where he has three years left on his contract, has made matters worse.
Head coach Howe, who is desperate to keep a player who has played a vital role in the club's recent return to the top, has spoken cautiously about the situation publicly but is unlikely to condone a breakdown in the team ethic he has sought to establish during his time in charge.
Indeed, speaking to reporters before leaving Seoul after Sunday's 1-1 friendly with Tottenham, he said: “You have to earn the right to train with us.
