It's important to separate the criticism of Redknapp into three sections; self serving manager who is happy to take the plaudits but refuses responsibility when the shit hits the fan; Redknapp the manager, who, of course, has done much better than we could have hoped for but is still tactically inept/naive/stubborn, which has contributed greatly to our recent struggles; His comments about the fans and club. These are often thoughtless and said without necessity. Supporters will always vent their emotions, football is an emotional game that thrives on the immediate, he should understand that slagging those off who 'pay the wages' is a terrible thing to do.
But...
No one (I don't think) hasn't appreciated where we are now compared to where we were. I also think that the grumbling has been kept largely among ourselves whilst the support at the ground and away has remained, mostly, pretty good. It has been difficult watching inexplicable performances but we reserve the right to make noises when tactics that clearly aren't working are continuously used or players not rested when clear to most people that rotation is required.
I would still like a fresh start next season; I don't see us going any further under this regime.
