What do you mean by that?
I think he's saying that when a club hits a rough patch the fact that the complaints are roughly the same as other clubs in said rough patch are broadly the same never cease to amaze.
its all the same, regardless of manager its always too cautious, too much long ball, boring football etc. Just one of the quirks I've noticed, perhaps all managers fail in the exact same way but its a little curiosity I found amusing
