The fact that you're asking if it's true means you have had your head in the sand for the last 2 years or so.
Let's look at the facts:
Keegan - proved them to be utterly shameful liars in a court of law
Relegated
Shearer - completely ignored, not had phone calls returned about position
What we are left with is a bunch of people who actually gave a s*** and don't tell me that's not true as several people on here, myself included felt that about the players who brought us back up.
This group of players, some of who were on large contracts would not be willingly, or perhaps most importantly sold by their current manger as he sees how important this team spirit thing is.
Hughton - Surprise, surprise, just before being sacked stories of 'player power' appear in certain newspapers. He is then sacked with some rubbish about next level and losing control doing the rounds
Pardew - appointed. The dismantling of the group of players begins. Goes on to vomit and s*** varies quotes about the club/players and then, surprise, surprise again, the opposite happens. Rants on about the size and altogether wonderfulness of deals being offered to the players
Carroll - Local lad, told him to f*** off to anyone who offered silly money. Tried to make it appear that he wanted to leave. Carroll talks about the fans knowing the truth.
Nolan - Pivotal figure in dressing room regardless of opinions on ability/fitness. Club understandably want to reduce wages etc, Nolan wants to get a good deal. Nolan out, compromising which normally happens between the player and club in this situation doesn't happen. Utterances about age, money, contract length and not willing to compromise from club. Nolan denies and talks of fans knowing the truth.
Enrique - Although this started a while ago, is posturing for a better deal, then sees the team being dismantled around him and probably wants out. Who can blame him. Victim of Pardews contracting offerings speech, which it turns out was the same contract offered to him before.
Barton - Along the lines of Enrique, only decides to get more militant on twitter. Speaks about fans knowing the truth. Booted out, oh look the club source is quoting again. Not the clubs fault......
Other players such as Routledge talk about the truth and how the club is being run as well.
I'm sure I've missed out a few links quotes etc that will back this up, but how ANYONE can believe the club is utterly beyond me.
I don't blame Barton, I like his style and how he's gone about starting to expose them.
As for this season, I reckon apart from this team becoming the best of mates in record time and hardly any injuries we're pretty much f***ed.
Just who pulled the plug on the contract the club or Barton ? could be both parties are as bad as each other
