The Reds face Fiorentina on Wednesday for their last game in this year’s competition.
“I am convinced we will have Champions League football back here next season,” said Benitez.
“We have a good team, a good squad and we can win games in a row now. We have not lost in six and kept three consecutive clean sheets, that is positive and an improvement on what was happening a few weeks ago.
“We know what it means to play in the Champions League. The players certainly understand.
“We have the right experience and I am confident we will finish in the top four, at least, so we must concentrate on our league games to achieve that.
“We have Arsenal next, then Wigan in midweek before Portsmouth away the following Saturday. We must win those games to get ourselves back into a strong position to make sure we do qualify for the tournament next season.”
