If you want an underdog story in the Champions League last 16, then Tuesday's action should not disappoint.
Salzburg are likely to have the support of most neutrals when they visit heavyweights Bayern Munich in the second leg of their tie, having drawn the first leg 1-1 in Austria.
Inter are less used to being the team trying to spring the upset, but their task is a much taller one against a Liverpool side holding a 2-0 lead from the game in Milan.
And as the Opta data reveals, neither Salzburg nor Inter have much statistical reason for hope of progression.
Bayern Munich v Salzburg
Bayern staved off a surprise defeat in the first leg thanks to Kingsley Coman's late equaliser, and history is firmly on their side in the return match.
Indeed, Bayern have won all five of their games in European competition when hosting an Austrian opponent, scoring 15 goals and only conceding three in return. They have also progressed from five of their previous seven Champions League knockout ties when drawing away from home in the first leg.
Should Salzburg do what is considered close to the impossible and prevail at the Allianz Arena, they will end a long wait for Austrian sides in Europe's top competition. They are looking to become the first Austrian side to progress beyond the last 16 in the European Cup/Champions League since Austria Wien in the 1984-85 campaign.
Salzburg are, however, winless away from home in the Champions League this season (D1 L2) and have only won once away from home in the competition across the last two campaigns (D1 L4) – a 3-1 victory at Lokomotiv Moscow in December 2020.
Bayern talisman Robert Lewandowski was kept abnormally quiet in the first leg. He did not attempt any of Bayern's 22 shots, marking the first time in his career he has not recorded a shot attempt in consecutive Champions League appearances (77 minutes played v Barcelona and 90 minutes v Salzburg – zero shots).
Keeping Lewandowski under wraps for a third successive game in the competition seems highly unlikely, but Salzburg will almost certainly need to do so if they are to defy the odds.
Liverpool v Inter
Jurgen Klopp was keen to reject any talk of Liverpool being in a comfortable position in this tie following a 2-0 win at San Siro.
But all the signs are against Inter pulling off a turnaround at Anfield. Only one team in Champions League history has lost the first leg of a knockout stage tie by two or more goals at home and still gone on to progress, with Manchester United doing so against Paris Saint-Germain in the 2018-19 last 16 (0-2 at home, 3-1 away).
Inter's record in England does not inspire optimism. The Nerazzurri have lost four of their previous five away games against English sides in the Champions League (W1), although their victory in this run did come the last time one of these fixtures came in the knockout stages of the competition – 1-0 v Chelsea in the last 16 in 2009-10; a season in which they went on to lift the trophy.
If they are to turn the tie on its head, then Edin Dzeko may be the man to provide the goals. He has scored in three of his last four starts at Anfield across all competitions, including the most recent two.
The Bosnia-Herzegovina forward has not finished on the winning side in any of these three games, however, drawing 2-2 in 2012 and losing 2-1 in 2015 with Manchester City and losing 5-2 with Roma in 2018.
And as they discovered in the first leg, Inter will be coming up against one of Europe's stiffest defences. Since the start of the 2017-18 season, Liverpool have kept more clean sheets in Champions League home games than any other team (15 in 24 games). In fact, among teams who have played more than 10 home matches in the competition in this period, their clean sheet percentage of 63 per cent is also the best of any side.
