Parma coach Francesco Guidolin was left fuming with their performance after defeat to Roma.
He said: "I think this was our worst performance of the season so far. Maybe we felt subconsciously sated at being in that position and knowing we could not be overtaken even with a defeat.
"We got here a little tired, it was not a performance up to the standard of our last few months."
Second half goals from Nicolas Andre Burdisso and Matteo Brighi secured the result at the Olimpico.
"Roma deserved to win. We were never in the game and did not give the signals of a fightback that we usually do. This was not the usual Parma," continued the Coach.
