Rooney has been in contract negotiations with United for some time now and Press Association Sport understands considerable progress has been made in the last few days.
It is understood that Rooney agreed the outline of a five-and-a-half year contract worth #300,000 earlier this week.
But if any formal signing or announcement was imminent on Friday, Moyes was giving little away.
In fact, the United boss was far from happy to talk about the matter on Friday afternoon.
After repeated questioning about Rooney, Moyes said: "I'd only be repeating myself again (if I answered) your question."
Moyes was determined to focus on Saturday's Barclays Premier League game against Crystal Palace, rather than talk in depth about Rooney.
Palace looked destined for relegation towards the end of 2013, but manager Tony Pulis has turned things around at the London club.
Moyes has been impressed with what the former Stoke boss has done at Selhurst Park.
"A lot of people were writing Tony off during his time at Stoke City but he hasn't half gone in there and made a few people eat their words," Moyes added.
"Results are what matter and you have to think about where Crystal Palace were and where they are now. What matters to Tony is results and he's very good at getting them."
