here's an other stat for you:
we have the largest wage bill of the league and 92% is a pretty strong stat, so why even bother, right?
point is that stats won't explain everything. watching our matches, it's pretty clear for the observer that we have a badly coached squad. you can spend an other 10m on wages, this wouldn't explain why cuadrado and chiesa NEVER play on the same side (i reckon they would make a deadly duo, it is certainly worth at least ONE try, isn't it), why we are forcing the build-up from the back before learning how to play against high pressure, why we aren't exploiting counters more with pacey players like morata, chiesa, cuadrado and cr in our team, why we can't stay compact even if our life depended on it, how can't we stay concentrated for 90 minutes, how can't we string 3 passes together in the opposition box, why we are forcing the hybrid setup despite being way too vulnerable with it, how come that we never have more than 1-2 in-form players, etc. these are mostly down to bad preparation, and can't be explained by stats.
if you want to explain something with stats, try to find a stat for rookie coaches in top flights. some ideas: gattuso, inzaghi, leonardo, ferrara, stramacconi. you can put zidane there too, wouldn't change the big picture too much.
