In the days since David Moyes was sacked as Manchester United manager there has been an outbreak of conspiracy theories coming out of Old Trafford in an attempt to explain the reason for his dismissal.
Ultimately, what it boils down to is the fact that the former Everton boss lost the support of his players - if he ever really had it in the first place - after he was appointed as successor to Sir Alex Ferguson last summer.
Former Red Devils captain Roy Keane called it just about right when he tore into the current crop of under-performing stars, suggesting that they "should be ashamed of themselves" following a series of poor performances this season.
Keane intimated that Moyes should've been given more time to turn things around, but in an era where player power rules the roost, the 51-year-old Scot looked doomed almost from the outset, as many of his inherited first-team stars struggled to adjust to the new regime.
There's a variety of opinions regarding which player(s) let Moyes down the most, but thanks to statistics compiled by WhoScored.com the eight biggest disappointments in the post-Ferguson era can be pinpointed, based on their drop in average rating from 2012/13 to this season.
