The People says Ba may be forced to stay at Newcastle after demands from his advisers for extra payments pushed his fee above £12million.
The Senegal striker has a £7.5m release clause written into his contract which can be activated as soon as the transfer window swings open on Tuesday.
But it's reported Ba's advisers want between £3m and £5m to conduct a transfer - ballooning the fee to a whopping £12.5m.
Potential buyers also face the nightmare task of trying to satisfy Ba's wage demands. He is believed to want a whopping £85,000 a week, having turned down Newcastle's improved offer of £70,000.
A Toon source said: "There are people in the dressing room who believe Demba Ba has let Mike Ashley and Newcastle down after the way they helped resurrect his career. They've been kicked in the teeth."
