That last point is very interesting because you've got it the completely the wrong way around.
Precisely the reason why many people have a "disdain for stats" is because many of those obsessives who would likely want to base every decision the club makes with regards to playing staff based on the handful of percentages they read simply don't understand them and don't know how to apply them.
Hearing things like "Otamendi was our best defender according to whoscored" and "this guy only has 76% pass accuracy so he isn't a Pep player" are painful to listen to because it's an oversimplification of what is a very complex sport.
I've moaned about the overemphasis of the importance of statistical analysis before and a big reason for that is because we have many posters who think they know enough about a player they've never seen simply by looking at his statistics on a website. It's not a super special formula which proves the worth of a player, it's a bunch of reflective figures which often have zero bearing on the future performances of the player.
For example, compare Bravo's pass accuracy at Sociedad to when he was at Barcelona. How did Barca's coaching staff know he was capable of changing his game and applying their principles to a very high standard? Because they take a hell of a lot more into consideration than just a couple of numbers. Otamendi has been a good example because there doesn't seem to be any widely published collection of statistics which would indicate just how inexplicably amateur his positioning has been in the majority of the matches he has played for us. However, I can't be arsed to go into that because he seems to be a favourite and, to be fair to the guy, I think he has been superb in nearly every game since Monaco at the Etihad.
This is precisely why analysists play a specific role within a club, rather than making the decisions by themselves; these figures are useful tools and not the single pillar with which to hold up any knowledge you think you have on the game and it's players. And you know what? The people Pep works with and the people the club hire to carry out this analsyis do actually know what they're doing and are qualified for that role. They don't just think they know what they're talking about simply because they have access to a couple of websites and therefore think that they don't have to actually watch player play because they're seeing the game for what it really is:
And it's so, so much more than that.
