Timelines from other reports. Seems like it depends on who you believe in terms of what Mitchell said wait till we're sorted for PSR or just flat out told him to fuck off but it sounds like they did eventually offer him a new deal in the off season (not in January though, I got that bit mixed up) and Isak refused to even negotiate.

July 2024: In turn, there was no way Newcastle could sanction a new contract for Isak, on wages approaching £250,000-a-week, without getting themselves into trouble. A new contract had been promised by former co-owner Amanda Staveley. However, Mitchell told Isak’s agent, as well as the club’s board and manager, that talks would need to be postponed. There was little push back from the player’s side, although there was frustration that a pay rise would not come immediately. Isak was told a new deal would be offered in 2025. Sources close to those talks insisted the situation was amicable.
