As United's week-long stay in Sydney took them to a public training session at the Allianz Stadium, which attracted more support than the seasonal average of any side that plays there regularly, executive vice-chairman Ed Woodward set to work on the urgent transfer business that demanded his early return to Europe.
Given Woodward was due back in the UK on Sunday anyway, it was a significant move on his part which suggested a major piece of business.
And, speaking at a press conference to preview Saturday's encounter with the A-League All Stars at ANZ Stadium, Moyes for the first time endorsed the fact United had made a bid for Fabregas.
"I couldn't tell you exactly," said Moyes, when asked for a progress update. "I am in contact with the chief executive who has been dealing with it. I will hopefully know a little bit more in the next day or so."
Although Barcelona coach Tito Vilanova claimed earlier this week that Fabregas had informed him of a wish to remain at the Nou Camp, a position which was subsequently endorsed by Arsene Wenger, United are working on an alternative assessment of the situation.
They are of the opinion Fabregas is open to the idea of a move, and Barcelona might well be too given their need to balance the books following Neymar's £50million summer arrival.
Speculation about a mammoth bid for Gareth Bale continues to swirl too, while Everton duo Marouane Fellaini and Leighton Baines have also been the subject of repeated links.
So far, United's only signing of the Moyes era has been Uruguay Under-20 defender Guillermo Varela, who is now on a break after competing at the recent World Cup tournament in Turkey which England were so poor at.
With less than a month remaining before the Premier League opener at Swansea, followed closely by meetings with Chelsea, Liverpool and Manchester City, Moyes is aware he is behind schedule.
