Well isn't that the point of the moaning? Moan that we are crap, sign a couple of players, watch them be rubbish and then start the moaning again about signing bad players.
All of it is justified. We are never happy because there is zero to be happy about. Don't get me wrong there are loads of clubs in worse positions than us but it has been decades of turgid boring stuff with very few lights at the end of the tunnel. Even when we do "achieve" something like finishing 4th we then fail to qualify for the Champions League. We get a world class manager and we play some of the most boring stuff ever seen etc.
I totally get the moaning as the pattern repeats itself. Right now we cant seem to spend any money, have an incredibly divisive manager in charge, a rubbish squad with a couple of gaping holes in (that have been there for a few years) and one of our players in a legal limbo so we can't even do anything there either.
Its deffo moanworthy.
