Yep, I was guilty of thinking Chamberlain was already ready to be a first team regular following his performances when he came into the team after Christmas, particularly after his performances against United and Blackburn.
But the away games to Sunderland seemed to knock him off his stride, I still think he's got it in him right now to have a great game, or great moments within games, but he has not yet got the force of personality or belief in himself to be relied upon to turn games around.
From what I've seen of him in interviews he strikes me as the type of character who might have a tendancy to dwell on mistakes, or overthink his performances.
Needs to be allowed the time and space to develop without the pressure of having to carry a slightly dysfunctional team.
