Alexander Isak wants £ 300,000 a week to sign a new contract with Newcastle, which understands Talksport.
Eddie Howe and the tone owners are determined not to lose the much-needed striker this summer, but a deal of that size would break the wage structure of the club.
If the magpies succeed in preserving this summer, in the midst of strong interest of Liverpool and clubs in Saudi Aarabia, they would be in a much more difficult situation next summer if he did not sign an extension in St James' park.
Isak is under contract in Newcastle until June 2028, after he has registered a six-year-old deal with the Tyneside-outfit after he became at Real Sociedad for £ 63 million in 2022.
Liverpool has informed Newcastle with regard to the striker and the club that they are ready to dive with a bid with a big money if the tone changes their 'not for sale' position.
The 25-year-old was not present for the recent friendly defeat of the Magpies against Celtic after he had to return through Howe's home because of the constant speculation about his future.
