The Reds have had a disappointing start to the season and are out of the Champions League already and are in seventh spot in the Premier League table.
“If we get back to our full-strength team, and we get people fit, we’re confident we are good enough to finish in the top four,” he said.
“(Fernando) Torres’ return is massive for me, massive for everyone else. He’s our main man, he’s our top scorer and we need him back fit and firing.
“If that happens I’m sure we’ll move back up the league and get in to the top-four places. Without a doubt that has to be the main aim this season.”
“It’s obviously important for the club financially (to be in the top four) and having played in the Champions League for such a long time, I’m desperate to play in it again next season,” added Gerrard.
“In the six games prior to the Fiorentina defeat we had gone unbeaten, including three successive clean sheets. We have been improving.
“It was a shame we lost it at the end, because we wanted to use the game to prepare for Sunday.
“But we will be right up for the Arsenal match. If we can get three points there and then take that into the Wigan home game next Wednesday, we can turn a corner.”
