I have no idea from which season these stats are, or if they cover both his seasons, BUT:
The second stat is a rather poor stick to beat him with. We're the team with the most backward passes, but the top teams we'd ostensibly like to compare ourselves with, have very similar stats, and the current top 6 are all in the top 7 teams with most backwards passes.
Why?
Because they enjoy more possession = translates to more backwards passes. It doesn't say much of anything about his style or his performance as a manager of Manchester United – or rather, if anything, it reflects well on him.
The shots on goal stat is horrific, granted, but some would say LVG did not have the player material to enact his philosophy totally, and with the Liverpool game I think we saw the potential that his system had.
I think he was about to crack the code, and that his third season with us would have been fantastic.
But it's history already.
So.
Meh.
