Alisson says Liverpool must rediscover their consistency to turn around their poor season, calling on the Reds to draw on the experience of recovering from a disappointing 2020-21 campaign.
Having won both domestic cups and finished as runners-up in the Premier League and Champions League last term, Jurgen Klopp's team have endured a dire start to this season.
Liverpool sit eight points adrift of the Premier League's top four ahead of Sunday's trip to Tottenham, and Alisson says Klopp's men must bounce back in the same manner they did two seasons ago – when they finished an injury-disrupted campaign in third.
"We always have belief," Alisson told Sky Sports. "We have the understanding that things are not going so well for us so far.
"We have to be realistic. We have to be humble as well, to accept it, to fight more and to recognise what is going wrong and to change it.
"That is part of our team, being humble, fighting. We know that sometimes we cannot be the best on the pitch, but we will be the ones who fight the most. This is what we have done so far, and it worked out in other seasons for us.
"We can't forget the season we had before the last one, when we had to fight a lot. We struggled in the competition because of injuries, because of outside circumstances, but we came back.
"Something we all have in common, something we all agree on, [is] that we have to find our consistency again.
"Everybody is used to seeing it in our team. We, the players, and the people as well. A consistent Liverpool, conceding only a few goals, keeping clean sheets, scoring, winning games."
Liverpool are still yet to win an away Premier League game this season, their worst such run from the start of a campaign since 2006-07 (a sequence of seven), and would slip 13 points behind third-placed opponents Tottenham with a defeat on Sunday.
Klopp's side are therefore under huge pressure to claim a result in north London, but Alisson says they must shut out the noise as they bid to change their fortunes.
"It [pressure] is part of football," he added. "It is not something that is easy to deal with. But we have all played football for a while now, and I understand that this is part of it.
"You are going to have pressure from the outside world, from the supporters, from the media. Only playing for a big club are you going to have this kind of pressure.
"I see it as normal, but we have to fight back, and our response has to be on the pitch with performances. What we can't do is let the criticism affect us and bring us down more."
