Newcastle United is keeping its own counsel over claims from
However, Press Association Sport understands that the Magpies were less than impressed by both the player's comments after the 2-2 Premier League draw at Everton and subsequently those of his representative.
Ba, who scored both his side's goals after coming off the bench at half-time, revealed after the game that he had 'not been so happy with some things' beforehand, but agent Alex Gontran went further.
He told BBC Sport: "Since returning from the Africa Cup of Nations, Demba doesn't understand the management.
"If he continues to be a substitute all season, we'll look at other solutions."
The pair were, of course, two of the stars of last season's charge into the Premier League's top five, with Ba plundering 15 goals before his departure for the Africann Cup of Nations and January signing Cisse contributing 13 during the second half of the campaign.
However, Cisse's arrival from Freiburg prompted a change in Ba's position - he played much of his football wide on the left - and he added only one more to his tally before the end of the season while also providing his strike-partner with fine support.
Pardew has tried to employ him in a more central role in recent weeks, but Gontran claims it is that change which has upset his client.
He said: "How could you put your best striker with full confidence on the left wing?
"The choice to put Demba on the left last season was good for the club because Cisse scored 13 goals.
"But there was a lack of recognition for Demba. It is more difficult to play well when you don't have the confidence of your staff.
"Demba is happy at Newcastle. He is playing in the Premier League with lot of fellow French speakers and he loves the club's supporters.
"He would like to start every game, but he respects the choice of the coach, even if he does not always understand or agree."
Newcastle spent much of the northern summer listening to speculation that Ba could leave Tyneside as a series of clubs were linked with a move to trigger the £7.5 million ($11.65 million) release clause in his contract.
The expiry of that clause and the player's continued presence was greeted with a huge sigh of relief, although also a sense of disquiet at the roles played by several people claiming to represent him.
Indeed, Ba himself at one point spoke out to distance himself from one particular party.
Newcastle heads for Madeira and its opening UEFA Europa League group stage clash with Maritimo on Thursday evening (Friday morning AEST) with a new cloud hanging over a difficult start to the season, and there is little doubt that while it is maintaining a public silence over the Ba issue, that will not be the case behind the scenes.
