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.
And 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."
Nevertheless, United head to Sunderland looking to avoid a third successive Premier League defeat, something they have not experienced since 2001.
It is anticipated Wayne 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 Friday afternoon, Moyes could offer no injury bulletin.
