Two protest banners were flown over Old Trafford this afternoon despite Manchester United's 4-1 win against Aston Villa.
Some stars have taken to Twitter to show their disappointment and to show their support for the banners that have flown over Old Trafford today.
I must say, I think the Moyes banner exercise lacks class, and is unbefitting of a club of Manchester United's stature.

Moyes has made sure the plane flying over Old Trafford will be piloted by Tom Cleverley so it should miss by a mile #MUFC

Manchester United manager David Moyes is under pressure after a poor season.
Plane number one over Old Trafford... http://t.co/CTPiZ7Ohls
Two groups of Manchester United fans have chartered separate planes to fly over Old Trafford today with competing banners. One will read ‘wrong one: Moyes out’. Manager David Moyes is under pressure after a poor season.
A second plane will also carry a banner over Old Trafford on Saturday, although its message will be "completely different", ITV News can disclose.
The flight will take place in tandem with the one carrying a "Wrong one - Moyes Out" banner seen by ITV News earlier today.
However, it is unclear whether the people behind each have co-ordinated with one another.
The exact wording on the second banner, which will be carried by a different company, is yet to be revealed.
The pilot due to fly a 'Moyes Out' banner over Old Trafford on Saturday said he would also carry a banner in support of the manager if he was asked to.
Speaking to ITV News sports correspondent Ian Payne, Chris Mustow said his company Air Ads had declined some "colourful" requests for messages in the past.
A pilot tasked with flying a 'Moyes out' banner over Old Trafford says his company received the call two days ago - shortly after United went down 3-0 at him to rivals Manchester City.
Air Ads' chief pilot Chris Mustow also told ITV News' Ian Payne that, while the company had to be wary of public order issues, he was confident "we're not going to cause a riot".
Manchester United manager David Moyes says he's aware of the protest planned by some supporters during the game with Aston Villa at Old Trafford.
A relaxed looking Moyes acknowledged that fans have the right to protest but insists the club is at the start of a long journey with him at the helm.
