Here are some reasons why United will probably stick with van Gaal. Hopefully I'll jinx it:
1 The upheaval involved in appointing new staff.
2 The expensive of such an upheaval, including payoffs to those dismissed.
3 The worry over Giggs leaving (the board will believe this is bad PR).
4 The worry over van Gaal, Giggs and others publicly slating the board.
5 The negative reflection towards Woodward's decision-making post-SAF.
6 The board's - and others' - ambiguous feeling about José being United boss.
7 The friendship between van Gaal and Woodward.
8 Van Gaal's expedient excuses for underperformance which nevertheless might be believed by Woodward & co.
9 Van Gaal's guilt-trip: that he wasn't given the right players/the players aren't up to scratch/the media assassination campaign etc etc.
10 The supposed 'near miss' ("5th/6th isn't far from 4th"); a Cup win supposedly heralding a new age of success under LVG.
11 Van Gaal's 'understanding' that he'd be given 3 years to succeed ("It's a process").
12 The club would rather pretend things are ok than take difficult decisions in order to actually make things ok.
13 The club's policy is that public relations only truly matter when it comes to sponsorship, not when the fans are discontent.
14 The club's amateurish and timid laissez-faire approach to major decision-making.
15 The complacent belief that revenues and attendances will remain large despite little footballing success.
There's more, surely; a lot more, sadly, than there are reasons why United will dismiss LVG. I suspect that - incredibly - the board would view such a dismissal as a risk. Fingers crossed that I'm utterly wrong and that the club is more professional and bold than I thought.
