Alexander Isak is understood to be seeking a move away from Newcastle United, according to multiple sources with knowledge of the situation, as reported by The Athletic.
The Sweden international was notably absent from the club's pre-season fixture against Celtic and their subsequent tour of Asia.

While Newcastle cited a minor thigh issue as the reason, sources speaking anonymously suggest the decision was influenced by the player himself, who is believed to have preferred not to travel amid growing uncertainty over his future.
Although Isak remains under contract until June 2028, Newcastle have been pushing to secure him on improved terms. At the same time, the club is believed to be exploring potential replacements in the event of his departure.
Liverpool have emerged as the leading contenders for Isak's signature. The Reds reportedly made an approach to Newcastle, willing to pay up to £120m for the forward, though Newcastle have set their valuation at £150 million, the highest in British football history.
Isak is said to "give his priority" to Liverpool, and the Merseyside club is actively reshaping their squad following significant spending and expected outgoings such as Darwin Núñez and Luis Díaz. Despite signing Hugo Ekitike, the Reds are believed to be still willing to splash cash for Isak.
Arsenal have maintained a long-standing admiration for Isak. His technical quality, intelligent movement, and clinical finishing make him an ideal fit for Mikel Arteta's tactical system. The Gunners are searching for a prolific striker to spearhead their title ambitions, and Isak is high on their transfer shortlist.
Although the Gunners are said to be close to signing Viktor Gyokeres, a potential move for Isak can emerge if the deal breaks down for the former.
Chelsea have also shown an interest in Isak, monitoring his situation as they rebuild their attacking options. Reports indicate that while Chelsea, like Arsenal, admire Isak, the Swede's preference appears to be a move to Liverpool if he departs Newcastle. With other targets in mind, Chelsea may not have pushed as forcefully as Liverpool, but their ability to pay high fees and their need for a proven Premier League striker mean they cannot be discounted.
