A group of disgruntled United fans have clubbed together £840 to pay for a banner reading 'Wrong One - Moyes Out' to be flown above Old Trafford in the build-up to United's lunch-time kick-off against Aston Villa.
The message mocks a banner in the Stretford End which proclaims Moyes as 'The Chosen One' - a reference to the fact that Sir Alex Ferguson hand-picked Moyes to be his successor last summer.
The saga took another twist on Friday after it emerged that another banner, trailed from a different plane, will be flown over the stadium at the same time.
Reports indicate that a high-street bookmaker is behind the second banner.
The bookmaker is refusing to reveal the message their plane will drag across the skies, but it is understood to not be favourable towards Moyes.
If those fans who paid for the fly-by thought their stunt would push Moyes towards resignation, they were wrong.
"All it has done is strengthened my resolve to get the job done right," a defiant United manager said at his pre-match press conference on Friday.
"I'm more driven to succeed than ever.
"I want to change the position we're in just now. I really do believe we can do that."
Moyes refused the opportunity to criticise the fans who have planned the 'Moyes Out' stunt.
"I've heard of it and what they're saying about it," he said.
"It's a long journey here and this is just the start of the journey."
