Roma coach Paulo Fonseca accused his players of lacking courage after their 4-0 defeat at Napoli.
Lorenzo Insigne, Fabian Ruiz, Dries Mertens and Matteo Politano struck Napoli's goals.
“Quite simply, we didn't show enough courage and did not do anywhere near enough to earn a result against Napoli," Fonseca told Sky Sport Italia.
“We weren't the best team in the world before this game and we are not the worst now. Every match is a test for this team, not just against the biggest opponents.
“It certainly wasn't a good performance, as we lacked aggression, lacked courage, so we need to learn from this and correct our mistakes next time.
“We didn't close the lines, we weren't tight or aggressive enough, so we made it easier for Napoli. The strange thing is, we started really brightly, but then after that we couldn't string three passes together.
“Napoli are a great team, but we made defensive errors that gave them confidence and we were always struggling from then on. When we did have the ball, we gave it away again almost immediately and that allowed Napoli to go on the counter.
“Our defence became a back five and sat too deep. We invited Napoli to go wide and then our defence wouldn't be aggressive enough. We had a lot of problems especially down the right channel. The five at the back remained in their zones, their positions and that can't be right.
“Edin Dzeko was out for a while, he played a little bit in Romania on Thursday, but was not in the best condition."
