A 3-1 reverse in Sicily ended Napoli's six-game winning run in all competitions - including a penalty shootout triumph over Udinese in the Coppa Italia - and Benitez is keen for his squad to take a positive result back to the Stadio San Paolo next week.
They travel to Turkey for the first leg of their last 32 tie to face a Trabzonspor side who are well off the pace domestically, sitting fifth in Super Lig, 14 points behind leaders Besiktas.
"After our defeat to Palermo I was very angry but we must not forget that we came from six wins in a row," said the Spaniard.
"To get a positive result will help us to increase our confidence in this competition. The Europa League is a long path where every game is crucial, being favourites means nothing.
"We have seen many Trabzonspor games, they are a team that has a lot of intensity and will be highly motivated against us.
"But I am calm because the signs in training this week are positive."
