Quite an incredible post.
To say that it is a mess suggests some inside knowledge. The O.P. includes nearly zero insight into the football operation.
It's not even really coherent to complain, to that extent, about current results. We are playing at our highest level for a decade and still competing for the league. In terms of European results we are a victim of our own success.
The closest this gets to a genuine complaint is in regard to injuries. What does that amount to? Any management needs to tolerate a level of risk. In our case it has worked out badly.
