Does the atmosphere at Selhurst benefit the away team?

Seems it does little to inspire the home team despite their statements to the contrary – familiarity breeds contempt? The away fans seem to find a voice they don’t have at other away grounds, and I’m sure the away team players, far from being intimidated, are motivated by playing in a ground with an atmosphere rather than a library.

From what I see, a lot of teams really seem to play their best football at Palace, and very rarely teams appear flat (apart from Stoke maybe).

Thoughts?
