Liverpool have been granted what appears to be a free run at Newcastle striker Alexander Isak after he sensationally asked to leave St James' Park. And with Manchester United among the clubs already ruling themselves out of a move for the £120m forward, Arne Slot's Premier League champions could continue their remarkable transfer window by bringing in the Sweden star. Should that happen an even greater emphasis will be placed on outgoings, however, with a host of names now being linked with departures. Yet Liverpool could also continue spending regardless without immediately falling foul of PSR regulations. Here are the big stories as Liverpool continue to be the main characters in the 2025 summer transfer window. Alexander Isak has opened the door to a sensational British-record transfer to Liverpool after informing Newcastle that he wants to explore a move away from St James' Park. Isak did not travel with the Magpies to Singapore yesterday for their pre-season tour, though the club insist his omission was due to a thigh issue. And the Reds are in pole position despite interest from Saudi Arabia. So in the era of PSR, where clubs are evaluated on not posting losses of £105m across a three-year cycle, how can they continue to spend as they attempt to equip Arne Slot with a squad capable of retaining their title? That they only signed Federico Chiesa, one of several players now up for sale, last summer has certainly helped but the key to their splurge is amoritisation and the book value of sales outweighing fees paid out that are spread across several seasons. The sales of Trent Alexander-Arnold , Caoimhin Kelleher and Jarell Quansah for a combined £61.5m, with more departures destined to follow, means the Reds could sign Isak and still add another player amid continued links with Crystal Palace captain Marc Guehi. And here is how things could look on the balance sheet. Luis Diaz is wanted by Bayern Munich and is keen to join the German giants while Darwin Nunez, Harvey Elliott, Federico Chiesa and Tyler Morton remain possible departures before next month's transfer deadline. A number of loan agreements are also likely to be struck for academy players as the hectic window is set to continue.
