Are you going to answer my question or not?
No - because what you've asked for is a pretty wide-ranging summary of Pardew's performance - save to say that I don't think absolutely every single thing he's ever done at Newcastle has been s***.
Simple question for you: Do you think any other manager currently managing in the Premier League would have played Dan Gosling today whilst HBA sits on the bench?
Knowing very little about the exact situation regarding Ben Arfa, but knowing that Pardew wants to win games and would probably play him if he thought he'd help to bring that about, probably yes. Whether he's right or not, whether he's managed Ben Arfa poorly or not etc etc are all separate questions.
And now, because this forum is the way it is, I have to go out of my way to emphasise that I don't necessarily agree with Pardew on this.
