It's just there to placate fans. Worthless. At least there is some proper backroom staff in now, however I doubt this represents a change in culture at the club.
A number of the goals I saw Palace score after he took over were just long punts down the middle. Obviously once Palace started winning the players gain confidence. It won't last.
He will be far better than Pardew. He's experienced enough to not be absolutely terrified of the job. I don't think he'll be anything special but I expect a more enjoyable football experience.
