Crystal Palace boss Roy Hodgson admits concern about player confidence after their hammering at Newcastle.
Newcastle proved too strong winning 4-0 on Saturday.
Hodgson said: Football results do dent confidence and a player's confidence, and good results do build confidence. Teams live on that rollercoaster of having their confidence attacked in some way by a poor performance, but they can start to get euphoric again when they get a good one.
We will need to make sure we put this into some sort of perspective and be very honest with ourselves and work out why it happened, because we really did not expect it.
We need to make certain then we don't find ourselves in a similar situation because as good as Newcastle are, there are quite a few other teams in the league equally as good with equally as good players, equally as well-organised, equally as physical and equally as capable of running a lot, so we have to bear that in mind and, if we're going to compete at all with these teams and in this league, we need to come to terms with it."
