Ramires is confident Chelsea can score the two goals they need to beat Napoli and progress to the quarter-finals of the UEFA Champions League.
The Blues are looking to become one of a handful of teams to overturn a two-goal first-leg deficit when they resume their last-16 tie with Walter Mazzarri's men on Wednesday.
They were written off by many after their 3-1 defeat at the San Paolo stadium two-and-a-half weeks ago in what was the death throes of Andre Villas-Boas' reign.
Since then, much has happened to give Chelsea hope they may be able to turn the tie around.
Caretaker manager Roberto Di Matteo's first game in charge against Birmingham in the FA Cup saw them stop the rot that had set in under Villas-Boas, while Arsenal went agonisingly close to overhauling a 4-0 first-leg deficit against AC Milan.
More importantly, Napoli also shipped three goals in Friday night's Serie A game against Cagliari.
Unfortunately, they also scored six, racking up their sixth successive victory in the process to go into Wednesday night's game in arguably their best form of the season.
But Chelsea midfielder Ramires has refused to be intimidated, pointing out his side beat Valencia 3-0 in their last must-win Champions League game in December.
He told Chelsea's official matchday programme: "We had our opportunities to score in Naples and we didn't take them, but I think if we play well, we will have lots more chances to score at home - especially with the support of our fans.
"I think back to December, when we won the games against Newcastle, Valencia and Manchester City with some excellent performances.
"I don't think it's too difficult to score two goals - or maybe even more - at home, so that makes me confident we can go through to the next round."
Despite watching his side net six times on Friday night, Napoli boss Mazzarri is far from happy going into next week's trip to Stamford Bridge.
He said: "I got angry because, even if the result was safe, we shouldn't have conceded the last two goals.
"We cannot relax even for a second, because that way we concede. We've got to reflect on that.
"I am not worried about Chelsea, but the fact is we cannot afford similar defensive errors against Chelsea."
