It was widely suggested that the Red Devils were weighing up a bid for the centre-forward at the end of last month, while a host of other clubs, including Crystal Palace, Everton and Newcastle United were also linked with a move.
And in particular, Austin has addressed the speculation concerning Manchester United, and states that a transfer to Old Trafford was never a possibility.
Speaking to talkSPORT, the 26-year-old said: “No, that was never on the cards.
“Not that I was aware of.”
He also revealed that he did receive an offer in the summer, but refused as it didn’t suit his family.
“I turned down a move which wasn’t right for me and my family,” he added.
“I didn’t feel it was right for me to go, so I stayed at QPR.”
Austin has netted four goals in five games for the Hoops, and having entered the final year of his contract at Loftus Road, he could be set to leave the club on a free transfer next summer.
However, if his goalscoring form continues, Tony Fernandes, the QPR chairman, will not want to lose his prised asset for nothing and could be planning a lucrative new contract.
