In a bizarre series of events, reports emerged in Brazil claiming Dante had agreed to join United, with the player then going on radio to clarify the situation, effectively stating nothing would be decided until January 31.
However, Marcus Marin, the 30-year-old's Germany-based agent, insists the only discussions that have been taking place are with Bayern Munich over an extension to a contract not due to expire until 2016.
And even if was to express an interest, Marin feels it would have to be for the end of the season as a January move is a non-starter.
"There is no way that is going to happen," he told Press Association Sport.
"He is not going to leave Bayern in the window.
"At the moment, Bayern are the only people we have spoken to anyway because we are talking over a new contract.
"We are still waiting for an answer from them and, although things happen very quickly in football, until that situation changes, we cannot speak to anyone else anyway."
Moyes has not spoken about Dante, although, given the player is capable of operating in central defence, at left-back or in midfield, the attraction would be obvious.
If there is a positive to emerge from a fairly confusing picture, it is that, for one of Europe's best players - virtually certain to be a member of Brazil's World Cup squad this summer - United remain an appealing proposition despite their present struggles in the Barclays Premier League.
"Manchester United followed him two years ago," Marin said. "We were in talks with them, but then he ended up at Bayern.
"They are a very good club - and a very big club - so it would be interesting if they were interested in Dante, although I stress we have not spoken to anyone."
Moyes is undoubtedly going to be linked with huge numbers of players until the January 31 deadline given his obvious need to strengthen, which is recognised by virtually everyone - including former right-back Gary Neville.
Chelsea's Juan Mata is another big-name target, although a near B£40million fee is a hefty one, which would require United to break their transfer record.
