There are some managers who fit particular clubs but then don't fit others. I think that's what we need to think about at Palace. Why so much better under Roy? Answer that question and we probably find what we need to know.
My own presumption is our players are neither that intelligent or particularly hard-working, they need mentoring and pretty rigourous training. Firstly, that means whoever we get the coaching has to be right. I'm also thinking too young won't work - as the players seem to need a guide.
When I think about it, managers like Rodgers or Rafa fit the bill. Possibly Cooper. For me, Potter is too flexible tactically. I don't think most of our players want, or need to, make their own decisions on the pitch. I'm not saying them all - I mean in general.
I feel like I'm being hard on our players - it's just a personal observation from the last few years. Our players seem to fold with too much responsibility - think about things like our penalties, or when decisions go against us. These things really show on the pitch sometimes - in the performances. Set plays a classic example. We lose concentration nearly every time, attacking or defending.
I would fancy our promotion side to have more leadership and determination than the current players - although recently we don't seem to give up too easily, which has been an improvement.

Red and Blue Army!

I think its a simple case that Roy is a top manager, and gets the most out of what he has at club level, good or bad squads. he was very defensive when we had a crap squad, and is being much more expansive with the current squad.

“That’s a joke son, I say, that’s a joke.” “Nice boy, but he’s sharp as a throw pillow.” “He’s so dumb he thinks a Mexican border pays rent” “ “Son… I say, son, some people are so narrow minded they can look through a keyhole with both eyes.”__ Forhorn Leghorn

I would like to suggest why putting an untried manager in the Palace job is a greater risk than say Arteta was at Arsenal.

Arsenal are a rich club with a squad many of whom would walk into our side. If Arteta had been a disaster the club could afford to sack him bring in a replacement and buy players to dig themselves out of a hole in the January window.

In fact with a squad of that talent they might not perform to the level of Premier league contenders but more likely do a Chelsea, e.g. mid table mediocrity.

I suggest that for us to achieve mid table safety most of our players need to perform well on a consistent basis and if they don't we would get relegated.

And unlike Arsenal we probably could not buy our way out of trouble.

Just a thought.

One more point

Am keen to know why pepole reckon the club tweeted pics of Hodgson yesterday and the smiley face and hearts? Do you think this means he is staying? I think his done a great job this season but I honestly think it’s time to move on

If you listen to other mid table fans they say the exact same thing about their team.

This season we seemed to turn up in the second halves and sleep in the first half.

Arteta wasn't 'mentored' for the City job under Pep was he? I think I must have missed that.
See I thought City let him go to Arsenal to have a crack at managing because they didn't believe he was experienced enough to take over from Pep. That was my take on it but what do I know?
