Demba Ba claims to have no association with an agent claiming the Newcastle striker is wanted by Manchester United.
Armand Doorn, a man said to work for Ba's management team, says the Red Devils have joined the list of clubs weighing up a January approach for the Senegal international.
With it having come to light that Ba has a release clause included in his Newcastle contract, speculation regarding his future on Tyneside has been steadily mounting.
He only linked up with the Magpies last summer, following West Ham's relegation out of the Premier League, but it is being strongly suggested that he could be on the move again during the winter transfer window.
Doorn has fanned the flames by claiming that Manchester United have joined the chase, with the Red Devils having expressed an interest without making a formal approach.
Ba, though, claims to have no working relationship with the representative in question and has sought to bring an end to the incessant rumors.
"Really, I don't know how desperate this "armand doorn" can be to talk like he's my agent!!" Ba posted on his official Twitter account.
"He's nothing for me. Stop lying and show respect."
