Everton supporter David D. Wallbank has caused a Twitter storm with suggestions that Manchester United manager David Moyes described the club's fans as a "f***ing disgrace" following the two sides' fixture on Wednesday night.

Moyes, who was subjected to chants of "sacked in the morning" and "David Moyes is full of sh*t" by his former club's support, allegedly met Wallbank in the Lowry Hotel after the game.

In the course of what was a casual conversation between the pair, Wallbank reports that Moyes expressed his disappointment at his treatment but praised Everton and new manager Roberto Martinez (warning: language NSFW):

Martinez's side came away from the clash at Old Trafford with a 1-0 win, leaving it five points ahead of ninth-placed United in fifth position. Indeed, no Premier League side can match the Toffees' record of just one defeat in the league this season.

The result only adds to the pressure on Moyes, following a period of results that had suggested the club were in the process of turning their season around—including wins over Arsenal and Bayer Leverkusen.

According to Wallbank, Moyes said he was slowly adapting to life at Old Trafford:

Much of the ill-feeling toward Moyes from the Everton support pertains to his summer pursuit of Leighton Baines and Marouane Fellaini—eventually sealing the capture of the Belgian.

There was a feeling at Goodison Park that the offers made for the pair were disrespectful in their valuation, as expressed by Martinez, per ESPN FC's Richard Jolly.

However, while it is important to note that the tweets remain uncorroborated, Moyes' frustration after a disappointing night would be understandable.

The Scot led the Toffees for over a decade, helping maintain strong league performances despite a budget substantially inferior to many of the side's rivals. He also represented the club at many public events over that period to great credit.

It will no doubt then be a major disappointment to see his former supporters turn on him over what was ultimately an unsurprising career move.

Football fans are, though, notoriously fickle, and—if there is truth to Wallbank's claims—Moyes will now be more careful about what he chooses to discuss with members of the public, with social media becoming an ever more common source of news stories.
