The Reds forward has questioned the club’s ambition after a disappointing campaign.
“It’s too soon to talk, I honestly think that we’re going to be fourth, but for me Champions League qualification isn’t so important,” he told Spanish newspaper AS.
“The really important thing is that the club makes a big effort and brings in important players, who will improve the quality of the squad.
“We need four or five top-class players to compete, better than we have here, who will make us grit our teeth and do everything we can to try and keep our places.
“Without reinforcements next year we will once again be fighting to be fourth.
“I want to fight next year to win the Premier League, to win the Champions League or the Europa League, but for this there have to be signings.”
He added: “There are so many circumstances and so many things that you have to take into account that it is too soon to talk about that. But I have this and three more years of my contract.
“I’ve left my home and it’s clear that I owe Liverpool many things, and I’m very happy here.
“The fans have treated my like one of their own, but I’m going to think about my future and hopefully it will be here. I think these fans deserve to win.
“Beyond thinking about me, I think the club deserve to get back to winning (trophies), but they know themselves that right now that it’s far off.
“The fans are worried about players going, it’s a problem when you start to fear that your players are going because you know it’s because the club is not moving forward, but I don’t think that is going to be the situation here.
“Since the arrival of (managing director) Christian Purslow, Liverpool have had an important boost, we signed with a big-money sponsor to match Real Madrid, then things are going to go forward.”
