Newcastle United striker Demba Ba denies talk of interest from Manchester United.
Armand Doorn, a man said to work for Ba's management team, says United have joined the list of clubs planning a January approach for the Senegal international.
"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."
