You got a points total last season that if I've read the stats correctly, was more than the points you achieved in winning the league in 4 of your last 13 winning campaigns and within just 2 or 3 points of several other of your winning campaigns.
Perhaps the manager & players didn't get as much credit as they should for that which probably doesn't help, but regardless, how much of this is down to the manager & players looking at the points gap they have to bridge to win the league (not that 100 pts will be necessary again in a hurry), looking at who's been bought in the summer and seeing an impossible task ? Made worse by liverpool looking like more of a potential threat this season and chelsea improving hugely.
Whether it's for those reasons or others, this does seem to be largely a mental issue because regardless of what shortcomings you see in the make up of the squad, how much the players are suited to the manager's style, whether he's been backed and where you think you need to add, your group of players should be playing far better and achieving far better results - the idea that a top class manager can't get a decent team out around de gea, pogba, lukaku, fred & sanchez seems strange. But whether the underperformance this year is down to manager or players, once it gets to this stage, it's always going to be the manager that goes.
I don't get this idea that he might turn it around. Turn it around to what ? Not a title challenging season. What use is a manager that can't kick on from a season like last season, regardless of who's fault it is, to a club like United ? Say he turns it around and you just about get a CL spot - what then ? There are a number of potential reasons he hasn't been sacked already but from a united fan perspective, surely none of them are good ones ?
