Newcastle's valuation of Isak is reportedly £150 million, and they are being cautious about selling him. Liverpool's bid was seen as a way to put pressure on Newcastle to sell Isak, who has been training with his former club, Real Sociedad, instead of joining his new team for preseason.

Liverpool's determination to sign Isak is evident, and they are willing to make life difficult for Newcastle to get their man. With the Premier League season restarting on August 15th, Liverpool is keen to secure Isak's signature before their opening match against Bournemouth at Anfield.

Isak's contract with Newcastle has three years remaining, giving the club a strong negotiating position. However, if Isak refuses to play, it could affect his value, and Newcastle may regret not selling him for Liverpool's bid.

Newcastle is also looking to replace Isak with a new striker, with RB Leipzig's Benjamin Sesko being a target, along with Manchester United. The Magpies are in a delicate situation, balancing their desire to keep Isak with the need to find a suitable replacement.
