Lionel Messi scored one stunning goal but then had a penalty saved as Barcelona failed in their attempt to produce a second Champions League comeback for the ages against Paris Saint-Germain on Wednesday. Meanwhile, Mohamed Salah and Sadio Mane eased Liverpool into the quarterfinals with a 2-0 win over RB Leipzig at the Puskas Arena.

Kylian Mbappe had netted a hat-trick as PSG stunned Barca 4-1 in the first leg last month, and he extended their advantage in this last-16 tie by netting a first-half penalty in the second leg to put last season's runners-up ahead on the night.

But Messi made it 1-1 with a ferocious strike from 30 meters, and the Argentine had the chance to put the visitors ahead after Antoine Griezmann was fouled in the area, only for the outstanding Keylor Navas to tip his spot-kick onto the bar.

Barcelona certainly went for it, but there was to be no repeat of their infamous recovery against the same opponents at the same stage four years ago, when they lost the first leg 4-0 but triumphed 6-1 in the return.

Their coach Ronald Koeman will nevertheless be encouraged by the way his team played on a cold, wet and windy night at an empty Parc des Princes.

Barcelona have been in a club crisis for some time, but they have a new president Joan Laporta, who will attempt to restore calm at the boardroom level, and they can still hope to finish the season strongly domestically.

Meanwhile, PSG are safely through to the quarterfinals as they look to go one better than last season and win the Champions League for the first time.

In the meantime, Liverpool advanced into the quarterfinals with a 2-0 win over RB Leipzig on Wednesday, completing a 4-0 aggregate victory.

Liverpool, leading 2-0 from the first-leg yet struggling in the Premier League after six straight home defeats, had several chances to extend their advantage in the first half but lacked sharpness in front of the goal.

Mane had an early chance but blasted over from a promising position. Leipzig knew one goal for them could set the nerves jangling for Juergen Klopp's side.

Liverpool keeper Alisson Becker did well to smother a shot from Dani Olmo in the 11th minute. Meanwhile, at the other end, Diogo Jota saw a header tipped over the bar by Leipzig keeper Peter Gulacsi.

Gulacsi then did well again to keep out a Salah shot after the Egyptian had been set free by a long ball forward from Thiago Alcantara.

Liverpool finally broke through in the 70th minute when Jota fed Salah, who cut across the top of the penalty area before drilling into the bottom corner.

Four minutes later, Mane made it 2-0 on the night when he met a Divock Origi cross from the right with a first-time finish, steering the ball home with the outside of his foot.

"It is a big result for us," said Salah.

"We came here after losing a few games in the Premier League. The team is not in the best shape, but we want to fight in the Champions League and also fight in the Premier League and see what can happen."
