Jurgen Klopp’s men are used to getting through to the knockout stages the hard way. In each of the past two seasons they have needed home wins to secure a place in the last 16 before going on to make the final.
However, the spectre of a free-scoring Salzburg, led by the Champions League’s top scorer in Erlin Braut Haaland spells trouble for an injury-hit Liverpool backline that has consistently leaked goals this season despite streaking clear at the top of the Premier League.
The Reds’ recorded a first clean sheet in 14 games in Saturday’s 3-0 win at Bournemouth, but lost another centre-back as Dejan Lovren limped off in the first half.
Should the Croatian miss the trip to Austria, Joe Gomez will be Klopp’s only fit partner for Virgil van Dijk in central defence.
Van Dijk narrowly missed out to Lionel Missi in the battle for the Ballon d’Or last week in recognition of the transformative effect he has had on Liverpool’s fortunes over the past two years.
But even the towering Dutchman has been incapable of stopping the steady flow of goals against in recent months.
Injuries have meant there has been a constant rotation of Lovren, Gomez and Joel Matip alongside Van Dijk, while the attacking impetus offered by full-backs Andy Robertson and Trent Alexander-Arnold leaves space in behind to be exploited.
Goalkeeper Alisson Becker also missed the first two months of the season due to a calf injury to further unsettle the backline.
The Brazilian is now back, but another injury to Fabinho has robbed the back four of the best player to protect them in the holding midfield role.
– Topsy-turvy first meeting –
“I forgot how it feels, to be honest,” said Klopp on finally ending the long wait for a clean sheet at the weekend.
“It’s great, we should have them more often. It was the most-used word in the dressing room by the boys – ‘clean sheet, clean sheet, clean sheet’.
“Obviously everybody was desperate for that, now we have it so let’s have it more often.
“The next game where a clean sheet would be useful is already around the corner, against Salzburg on Tuesday.”
That is easier said than done as Liverpool know from their first meeting with Jesse Marsch’s men in October.
The hosts seemed to be cruising to another Anfield win in the Champions League as they raced into a 3-0 lead, but Salzburg hit back to level at 3-3 before Mohamed Salah’s winner ensured Liverpool edged a seven-goal thriller.
Salzburg have scored 87 goals in 24 games in all competitions this season, 28 of which have come from Norwegian wonderkid Haaland in just 21 appearances.
The 19-year-old started on the bench when the sides met at Anfield due to injury, but came on to inspire the visitors’ revival in the second half and scored one of his eight Champions League goals.
“He’s not the only threat from Salzburg but he’s a proper one,” said Klopp of the danger posed by Haaland ahead of the sides’ first clash.
Salzburg need to win to make the last 16 on their first appearance in the group stage in 25 years.
A point would be enough for Liverpool to progress, but they need to win to secure top spot in Group E ahead of Napoli.
Given Liverpool’s paucity of clean sheets and Salzburg’s thirst for goals, attack would appear to be the best form of defence for the European champions.
