Roma management are unhappy with yesterday's extraordinary 4-4 draw with Napoli.
"This is not the real Roma and I cannot explain what happened. It was such a strange game," said general manager Rosella Sensi.
"We cannot use the lack of fans due to security measures as an alibi, as we need to know how to play away from home as well. We know our strengths and I won't criticise individuals, I have to reprimand everyone."
Roma defender Matteo Ferrari added: "A team that wants to win the Scudetto cannot make mistakes like this."
