The essence is, why did we pay so much for someone barely ready for Championship football? a) Was it a pure incompetence? b) Someone got a ferrari? c) Our scouts went to the wrong pub for intel?
If (a), then it must have been incompetence from bottom to top, and no-one dare saying the truth. If (b) it must have been a fleet of Ferrari as well, because you need to silence many people. If (c), so you got the wrong tips, did you do the real scouting work on the ground, write a decent report, someone did a 2nd opinion with all the sports data, and they were all fake?
