Newcastle coach, Alan Pardew has taken Demba Ba to task over his agent's outburst but been forced to concede the Senegalese could leave for a knockdown £7million in the January transfer window.
It was widely believed Demba Ba's buy-out clause expired at the end of July, but, as he prepared for Thursday night's Europa League tie against Maritimo, in Madeira, Pardew revealed that it kicks in again in the New Year.
The Newcastle manager was delighted with Demba Ba's two-goal response to going on as a second-half substitute at Everton on Monday but less impressed with his agent Alex Gontran's subsequent claim that they may seek a move, if the 27-year old continued to be left on the bench.
Furious at such a blatant attempt to influence his selection policy, Pardew held talks with Demba Ba before leaving Newcastle Airport on Wednesday and made it clear he would not tolerate such interference.
The set-to came amid a continuing wrangle over Demba Ba's future, with the former West Ham marksman leaving club officials dismayed with his pay demands.
His current £50,000-a-week contract runs out at the end of next season, and the figures he has been asking for have evidently been branded unrealistic by Newcastle and clubs interested in signing him.
Meanwhile, Newcastle will be without strikers Demba Ba and Papiss Cisse for Thursday's opening Europa League group match at Maritimo.
Cisse has withdrawn from the squad because of illness, with his place going to Adam Campbell, while Ba is one of several senior players left behind.
Shola Ameobi will start on a night when 37-year-old goalkeeper, Steve Harper hopes to extend a European career which he admits he thought was over.
