Alexander Isak has not officially handed in a transfer request to leave Newcastle United this summer, despite publicly expressing his desire to depart the club amid claims of "broken promises" and lost trust. The Sweden striker made a statement on social media indicating dissatisfaction and a lack of future at the club, but Newcastle officials and insiders confirm that no formal transfer request has been submitted[2][3].

Isak’s announcement took Newcastle's hierarchy by surprise, even though his intentions to leave have been widely known behind the scenes for some time. The club has adamantly denied making any promises to Isak regarding a contract or an exit this summer, pointing out that his grievances involve former personnel no longer with the club, such as ex-co-owner Amanda Staveley and former sporting director Paul Mitchell[1][3].

Newcastle’s management is reportedly frustrated and irritated by Isak’s public airing of his frustrations, viewing it as damaging to his chances of securing a move, especially with Liverpool showing interest. The club has communicated that Isak will not be sold during this transfer window and will be welcomed back into the squad when he chooses to return to professional commitments[1].

Within the squad, reactions to Isak’s public position are mixed, with some teammates reportedly upset by how he has handled the situation. Club captain Bruno Guimarães posted a show of loyalty to Newcastle shortly after Isak’s message, underlining the internal division in sentiment[1].

In summary, while Isak has voiced a clear desire to leave Newcastle, the lack of a formal transfer request and the club's firm stance suggest that a resolution is yet to be reached this summer, with his future still in a state of uncertainty[2][3][1].
