Sheedy took to his official Twitter account to vent his anger (h/t Nick Lustig of the Daily Star).
Although the original tweets have since been deleted, a number of retweets have ensured that Sheedy's words will remain in the public domain:
RT @kevin11sheedy: In my 7 years moyes showed no interest in our youth team. R Hmmm interesting.— DeGuzman - Yondaime (@SirDeGuz) March 17, 2014
Such an attack may come as a surprise to the Scot, Sheedy having worked well under Moyes for seven years before the latter left to replace Sir Alex Ferguson.
The comments could be construed as representing a managerial policy that leans toward buying in the best possible talent, rather than recruiting from within—something that Manchester United have been renowned for over the years.
Renowned Dutch football coach Raymond Verheijen has also been particularly scathing of Moyes' staffing and methods, via his personal Twitter account:
Former coach Meulensteen would have had more to offer to United than all the current clueless & inexperienced nobodies on the United bench.— Raymond Verheijen (@raymondverheije) September 28, 2013
In 7 of 9 seasons at Everton: injury crisis after pre-season & very poor start of season. This pattern has clearly repeated itself at United— Raymond Verheijen (@raymondverheije) December 7, 2013
If you appoint a coaching staff, that has never won anything, to manage players who have won almost everything, you're asking for trouble.— Raymond Verheijen (@raymondverheije) December 7, 2013
Although the criticisms might be water off a duck's back to the hardy Scot, they paint a dreadful picture, and possibly go some way to explaining the poor start to his career on the Old Trafford hot seat.
At a club that has always prided itself for producing the best homegrown talent—think David Beckham, Paul Scholes, Gary Neville et al—the idea of a lack of interest from the manager at youth and academy level is an unpalatable one.
Of more immediate importance to Moyes, however, is getting his players playing a style that the Old Trafford regulars have become accustomed to.
Sheedy appears to think that's beyond him too:
Punt the ball up to Fellaini. Great viewing.— Kevin Sheedy (@kevin11sheedy) March 16, 2014
It's an incredibly testing time, but if Moyes can run the gauntlet and ride out this particular storm, brighter days could be ahead.
Those brighter days can't come quick enough.
