Despite their best efforts throughout the full 90 minutes, an increasingly desperate PSG astonishingly failed to break through the inspired Alisson Becker's goal - except for an offside effort by Khvicha Kvaratskhelia. The long-serving Liverpool number one made an outstanding nine saves at the Parc des Princes.

Luis Enrique's team, despite registering 27 shots, managed to score a total of zero goals. Meanwhile, Liverpool went home with the crucial goal from just one of their two attempts that evening. Harvey Elliott, coming off the bench, punished PSG's wastefulness with a dramatic 87th - minute winning goal.

Only once before in the Champions League had a team won a knockout game with a shots difference of -25 or more. Moreover, winning the first leg has been a positive sign for Liverpool over the past two decades. They have advanced from 14 of their last Champions League ties when winning the opening match.

The 2001 - 02 Bayer Leverkusen team was the last to eliminate Liverpool in such a situation. But while PSG failed last Wednesday evening, Southampton succeeded on Saturday afternoon. Will Smallbone took advantage of a rare defensive blunder to give the Premier League's bottom - placed team the lead.

However, Liverpool transformed in the second half. Darwin Nunez equalized, and then Mohamed Salah scored a match - winning brace from the penalty spot. This remarkable Egyptian became the Reds' third - highest all - time scorer and equaled the record for the most goal involvements in a 38 - game Premier League season.

The hosts' 3 - 1 comeback win against Southampton marked four consecutive victories across all competitions. But similar to their performance at the Parc des Princes, there were aspects of this display - particularly in the first half - that should have PSG feeling confident.

As surprising as Les Parisiens' first-leg loss may have been given their volume of opportunities, it was just the same old story for PSG in the Champions League, the one trophy that continues to elude them amid their non-stop spending sprees.

The perennial Ligue 1 champions can take inspiration from last year's tournament as they seek to complete a mesmerising comeback job on Tuesday, though, as they memorably lost 3-2 at home to Barcelona in the 2023-24 quarter-finals before advancing with a 4-1 second-leg success in Catalonia.

Coincidentally, Enrique's men thumped top-flight rivals Rennes by the same scoreline on Saturday, righting their attacking wrongs from the first leg as Bradley Barcola and Goncalo Ramos netted before the dazzling Ousmane Dembele netted his 19th and 20th Ligue 1 goals of the season in added time.

By making light work of Les Rouges et Noir, PSG extended their winning run away from home to an astounding 13 matches across all competitions, including each of their last three in the Champions League, albeit to more modest opposition in Brest, Stuttgart and Red Bull Salzburg.

In fact, none of the last 15 French teams to face an English club away from home in Europe has managed to win, although PSG themselves were the last to do so against Manchester United in December 2020, offering further hope of a Merseyside turnaround unless Alisson has another self-professed 'best performance of his life'.

Liverpool came out of their success over Southampton with no new concerns on the injury front, but Cody Gakpo was once again missing from the ranks due to his recent knock and is a serious doubt for the visit of the French champions.

Tyler Morton (shoulder), Joe Gomez (hamstring) and Conor Bradley (hamstring) make up a trio of guaranteed absentees for Slot, who bit the bullet at half time on Saturday and made no fewer than three half-time changes, including taking off Dominik Szoboszlai.

The Reds boss admitted afterwards that it may have been a mistake starting the Hungarian workhorse, who has seemingly reached his physical limit, so the door might be open for Paris hero Elliott to start in the number 10 position in midweek.

On the other hand, PSG come into the second leg without a single injury concern, giving Enrique the luxury of making multiple rotations for the meeting with Rennes as several big names were rested.

The electrifying Dembele will be among the senior starters to return to the fold, leading the line in place of Ramos, while Kvaratskhelia, Vitinha, Fabian Ruiz, Achraf Hakimi, Marquinhos, Nuno Mendes and Gianluigi Donnarumma are set to return after being dropped at the weekend too.

Reportedly admired by Liverpool, teenage sensation Warren Zaire-Emery captained Les Parisiens from a right-back role in the thrashing of Rennes, but the 19-year-old will now take his seat in the Anfield dugout.

Alisson; Alexander-Arnold, Konate, Van Dijk, Robertson; Mac Allister, Gravenberch; Salah, Elliott, Diaz; Nunez

Paris Saint-Germain possible starting lineup:
