According to British media talkSPORT, Isaac asked for a contract of 300,000 pounds per week before he was willing to renew his contract with Newcastle.
Newcastle decided to keep Isaac this summer, but such a high salary would break the club's salary structure. If Newcastle agrees to a weekly salary of 300,000 pounds, Isaac will become the top ten players in the Premier League, the same as Gallish and B Fee.
According to capology data, the current maximum salary player in Newcastle is Guimaraes, with a weekly salary of 160,000 pounds. Isaac currently ranks fourth in the team with a weekly salary of 120,000 pounds. If Isaac renews his contract with a weekly salary of 300,000 pounds, it will be nearly twice the current maximum salary of Newcastle.
