ROME, Oct. 17 (Xinhua) -- Napoli head coach Rafael Benitez said on Thursday he was optimistic about his side chance against Roma despite their inconsistent forms.
Napoli will play at Roma on Friday, and Benitez said his team are not in their 100 per cent best.
"I've always said that we are working to improve. We are still only at 75 per cent, I'm very satisfied," he said.
"We won at Milan even if with a little difficulty. Then we drew at home to Sassuolo. Italian football is hard, but we are optimistic ahead of Roma," he said.
Benitez played down the importance of the game which pits the league leaders against the second-placed team.
"If we win in Rome then we will return to Naples and prepare for the Marseille game," he said. "If we collect three points at Roma then we won't definitely win the Scudetto. If we don't win then we will just continue trying to get better."
The Spaniard said he will not assign a player to man-mark Francesco Totti who has inspired Roma to seven wins from as many Serie A games this season.
"Totti is a great player. We have to be defensively aware because he can make the difference. But we won't put a man on him, " he said.
"Roma are a fantastic pressing side and their organization leaves little space for their opponents. It is no coincidence that they concede few goals. They counter well, but so do we," he said.
"I don't think Roma will change anything to the way they play. They defend as a team and don't man mark. They are good at the defensive phase and we just need to find the right space," he added.
