There was none of the swagger seen in their last match, a 6-0 demolition of Arsenal.
Neither was there any indication, from their performance, that they were the champions-elect that the spectators at Selhurst Park were watching last night.
Against a team fighting for Premiership survival, Chelsea looked ordinary.
Very ordinary, in fact.
In the end, the Blues fell flat on their faces.
Crystal Palace pulled off a shock 1-0 home win, courtesy of a John Terry own-goal, to strike a massive blow to Chelsea's title hopes.
Palace's limitations were plain to see.
Their approach lacked the subtlety required to break down a team which kept 14 clean sheets prior to this mismatch.
