Going out of the Champions League to Olympiacos on Wednesday would be another blow to the manager's credibility.
But when asked if not overcoming a two-goal deficit against the Greeks would have any impact on his future, Moyes told a press conference: "My future has not changed one bit.
"I have a great job
I know exactly the direction I want to go in.
"The season has not been as good as I had hoped but I have ideas that I will put in place when the time is right."
It is understood that the United board are not considering replacing Moyes at this points despite a terrible season which has seen the team plummet to seventh in the Barclays Premier League with nine matches of the campaign left.
Moyes said in his press conference that he has had a lot of support from the United hierarchy, including his predecessor Sir Alex Ferguson.
"I speak with him regularly and when he is at the games," Moyes said of his compatriot.
"He has been very supportive
He told me it would be a difficult job before I came in, but he and (vice chairman) Ed (Woodward) are very supportive."
Moyes added: "We have big plans for years going forward.
"This is a club that works on a long-term vision, not a short-term one and that is why I was given a six-year contract."
