• Manager defiant despite growing unrest at Old Trafford • 'Supporters are entitled to fly-past protest' • Pictures of protest banner emerge on social media

David Moyes insists he retains the support of the majority of Manchester United fans.

A group of supporters have clubbed together to raise £840 to pay for a light aircraft to fly over Old Trafford on Saturday, trailed by a banner that reads "Wrong One – Moyes Out".

The United boss said fans were "entitled" to organise such a protest after recent results, but the Scot insists he is supported by most fans, the club's board and the playing staff.

"Everywhere I go I get great support from Manchester United supporters," Moyes said. "I was at a dinner last night for Darren Fletcher and there were Manchester United supporters who came up to me and said: 'Come on, keep going, we understand exactly the situation the club is in and team is in.'

"They were really supportive and every time I have been to Old Trafford they have been great. I am seeing a lot different from what a lot of people are saying but I understand that results matter."

Pictures of the banner that fans intend to fly over Old Trafford emerged on Thursday.

An aerial advertising company, Air Ads, told the Manchester Evening News that they received a call earlier this week requesting the banner to be made. Chris Mustow, chief pilot at Air Ads, said: "It was the middle of the week when we took the inquiry. They want it around kick-off, just after kick-off. It will be around 15 minutes overhead."

A statement from the fans on the Red Issue website said the decision was "borne out of accute frustration – frustration at the poor results, lack of fight on the pitch and the unavoidable signs the David Moyes isn't up to the highest standards required to manage Manchester United Football Club. A significant proportion of Manchester United fans have had enough and unequivocally want David Moyes sacked."

The protest organiser Wes Jones told the BBC: "The rumblings of discontent have started in the stands. We wanted to show that support isn't as 100% as Moyes would like to think."

The plane will have to be 1,000 feet above the stadium to comply with aviation rules. "We have had to use extra large letters just to make sure everybody can see it," said Mustow.

Asked about the protest, Moyes said: "I have heard of it and what they are saying about it, but this is something which is a long journey here, this is only the start of the journey. People can do that. They are entitled to do that."

Moyes, whose team lie seventh in the Premier League, insists the protest against him has only strengthened his resolve to turn United's fortunes around.

"I am more driven to succeed than ever. I want to change this position we are in now and I believe we can do that," he said. "I am hurting and the players are hurting but we are working hard."

Reports of unrest among the playing staff emerged following Tuesday's 3-0 defeat to Manchester City – the club's sixth home defeat of the campaign.

When asked if he retained the support of the playing staff, Moyes said: "Definitely. I have no reason to suggest anything else. We work together and have a great relationship."

It has emerged that another banner, trailed from a different plane, will be flown over the stadium at the same time by a high-street bookmaker.

The bookmaker is refusing to reveal the message the plane will drag across the skies but it is understood to not be favourable towards Moyes.
