West Brom have sacked Nicolas Anelka citing "gross misconduct" after the striker claimed on Twitter he had quit the club.
United's troubled start to the Barclays Premier League campaign led some to suggest the Old Trafford outfit may look to bring Ferguson back.
The 71-year-old quashed any of that talk during his extended interview in the United States this week, insisting Moyes was the right man to step in.
Moyes believes that statement will be proved correct.
"Manchester United is a good club," he said.
"I am sure they know they picked the right man for the job.
"Sir Alex was part of that process as well."
Moyes also says Ferguson's forthcoming book launch and sell-out theatre tour will not prove a distraction.
If his previous book Managing My Life is any guide, the press conference to launch the autobiography on October 22, the same day as Moyes is due to face the media ahead of United's Champions League encounter with Real Sociedad, will dominate the news agenda.
After that there are five Q&A evenings, in Manchester, London, Glasgow, Aberdeen and Dublin, that will also capture plenty of attention.
Yet Moyes does not see any particular problem with that. And he does not believe United's focus will be altered as a result of it either.
"Anything Sir Alex does is good for Manchester United," said Moyes on Friday. "He was an incredible manager. His success was fantastic.
"I don't see it being negative in any way at all."
There has been speculation Ferguson may re-open old wounds with Wayne Rooney, or the England striker's long-time adviser Paul Stretford.
In this week's interview Ferguson refused to back down from his claim Rooney asked for a transfer last season.
"If you are alluding to Wayne I see no problems with that whatsoever," said Moyes.
"Look at Wayne's performances. Look at the way he has played. I think he has been fantastic.
"I don't think anything that comes out will have any effect on us.
"To the Manchester United supporters, anything Sir Alex says is gospel. They love him and rightly so."
United head to Sunderland on Saturday looking to avoid a third successive Premier League defeat, something they have not experienced since 2001.
It is anticipated Rooney will have recovered from the shin problem that kept him out of Wednesday's Champions League draw with Shakhtar Donetsk.
However, as United did not return to the UK until Thursday evening, and are not due to train until this afternoon, Moyes could offer no injury bulletin.
"I have not seen him yet," said Moyes.
"I cannot give you an update."
United face a team who have been plunged into turmoil following manager Paolo di Canio's dismissal.
As Moyes knows only too well - his Everton team were beaten at the Stadium of Light last season at a point when Sunderland were still basking in Di Canio's arrival.
"Di Canio had just got the job and I lost that game," said Moyes.
"It was probably one of the only games I lost at Everton in the last 11 or 12 games.
"We go up there now with a new manager again, Kevin Ball, but he has been there [for a while].
"He's very experienced, he knows the club and he knows the players.
"He'll have watched all the games and he'll know what he has to do in this short-term period.
"Whether he gets the job or not, nobody knows but Sunderland look as if they played quite well in the last couple of games."
