The long-running saga over Bale's future took a fresh twist on Monday when it emerged Spurs were considering offers from more than one club for the 24-year-old.
Bale was thought to be nearing a world-record move to Real Madrid having reportedly spent the weekend in Spain to finalise the details of a switch to the Bernabeu.
But Press Association Sport understands Spurs have received a bid from at least one other club for the highly-rated Wales international.
Moyes made clear this was not from United when he spoke after his side's goalless Barclays Premier League draw with Chelsea at Old Trafford.
Asked if United had made a bid, he said: "No."
But, having not yet made a major signing since taking over at United, Moyes cryptically mentioned that he was still on the lookout for new players.
He said: "I have just said Manchester United are always interested in the best players.
"The board and myself would always be looking to sign who we think are the best players, whoever they are."
While people may interpret that to mean United could yet enter the race, the onus clearly remains on Real Madrid to push through a deal for their long-time target.
