After suffering the ignominy of becoming the first holders to exit the Champions League before Christmas, the Blues will bid to end the campaign with a European trophy for a second successive season.
Chelsea began the season in contention for seven trophies; the Europa League is the unexpected eighth and Wednesday night in Amsterdam is the Blues' final chance of silverware this term.
"All the season has been difficult, but now is almost the end of the season and we have to do everything to finish the job off," said Ivanovic, ahead of Chelsea's 68th game of the campaign.
"It was very disappointing for us to go out of the Champions League. We tried to motivate ourselves to do our best in the Europa League.
"We're in the final and we're happy about that. We will do everything to try to win the trophy. It's going to be very hard. We will play against Benfica, a very good team.
"It's very important, another final for the club and another chance to win a trophy.
"It's very important for us as a group to get the chance to finish the season with a trophy."
