Sunday Express Sport revealed last week that the Senegalese forward was asking for £90,000 a week.
Owner Mike Ashley, who has put the Geordies on a sound financial footing, was prepared to budge on his wage ceiling of £60,000, offering the player a further £10,000 a week.
But Ba’s advisors, who are asking for £5 MILLION for themselves when Ba moves on, have alerted other clubs the Toon No 19 has a £7million escape clause.

Are Demba Ba's Demands Pure GREED?
According to The Independent newspaper - the full cost of buying the Newcastle United striker Demba Ba could total a staggering £30m.
The Independent: "So far Newcastle have yet to receive a single phone call enquiring about the Senegalese forward.
"Newcastle have been unable to agree terms on an improved deal for Ba, following the 26 goals he has scored since his move to the North-east.
"When he moved from Upton Park as a free agent in the summer of 2011, Ba signed a three-year deal that was worth £40,000 a week.
"There has been a desire from his representatives to double that contract, a wage which is way above the ceiling set at St James' Park, and significantly above that of the top earner at the club, Fabricio Coloccini.
"The hidden costs that would come with any move away from Newcastle would change the financial landscape dramatically. It is believed the fees required to pay those representing Ba would be around £5m.
"A four-year deal at £80,000 a week, the figures his representatives are asking for, would mean any buying club would have to put together a £16m wage package. The entire package would cost more than £30m – and Ba would be entitled to half of the £7.5m transfer fee."
