Liverpool have struggled this season to keep the goals out; they have conceded 32 in 21 Premier League games; last season, in its entirety, they conceded 41. The Reds are now having to target a top-four finish instead of a title challenge, as they sit sixth, two points behind Manchester United in fourth and 14 behind Arsenal at the summit.
Ex-Reds defender Jamie Carragher has previously claimed that Slot will lose his job if they don't qualify for the Champions League.
He told Sky Sports: "If you don't qualify for the Champions League, having won the league the season before and spent as much as Liverpool, I don't think you've got a leg to stand on.
"The real worry I have for Liverpool in terms of qualifying for the Champions League is the three big things that stand out in the Premier League now are set-pieces, counter-attacking football and coming up against low blocks.
"Liverpool can't cope with any of them. What we're seeing is a team in the Premier League that's not suited to the Premier League.
"Once you start seeing what Manchester United and Chelsea have done in the last couple of weeks, you start seeing that Liverpool could actually finish outside the Champions League positions. I really fear for them. Once you start fearing Champions League qualification for next season, that's when I think we've got a completely different proposition when we're talking about the manager's job. That, for me, is completely different.
"If we're talking about not winning the league or challenging for the league, that is a collective responsibility, and Liverpool don't win the league every year. Not making the Champions League from [being] champions, spending £450m and having the highest wage bill in the Premier League, which is normally the biggest determining factor over where you finish in the league, I think you've got serious questions to ask."
