Liverpool substitute Harvey Elliott scored a last-gasp winner less than a minute after coming on to earn a fortunate 1-0 win against Paris Saint-Germain who dominated their visitors during Wednesday’s Champions League round-of-16 first leg match.

Elliott slotted the ball home in the 87th minute against the run of play after a layoff from fellow substitute Darwin Nunez for a scarcely-deserved victory in Paris.

Arne Slot’s team were kept afloat by keeper Alisson’s string of magnificent saves and scored with their first attempt on goal.

Luis Enrique’s PSG, who had won 18 of their last 20 competitive games, drawing the other two, were left to rue their missed chances from dozens of attempts as a tough return leg await at Anfield next Tuesday. 

PSG got off to a strong start with Liverpool’s attempt at a high press not lasting long.

The hosts had the first clear chance in the 16th minute when Joao Neves skied his attempt over the bar from Dembele’s cutback after the France forward had outpaced two defenders to break down the right flank.

Alarm bells were ringing for Liverpool and they again escaped punishment in the 20th when Khvicha Kvaratskhelia’s superb curled effort was ruled out for offside after a VAR review.

With Liverpool in survival mode, Alisson parried Neves’ 25-metre strike before denying Dembele. The ball went into the path of Barcola, whose first strike was blocked before his second flew over.

The Brazil keeper’s firm hand was there again to stop Kvaratskhelia and he made saves left, right and centre early in a one-sided second half.

Slot sent Curtis Jones and Nunez on for Luis Diaz and Diogo Jota hoping to shift the momentum, but PSG stayed a notch above.

Alisson, again, stretched to tip away Desire Doue’s missile 10 minutes from time and he also played a key role in the build-up to the goal.

With the clock ticking down, Nunez won Alisson’s long ball and played into the path of Elliott, who calmly slid the ball past Gianluigi Donnarumma.

“Full credit to the team,” Elliott said. “You could see they [PSG] had become a bit tired at the end. They were creating many chances.

“It was down to me to put the opportunity away and fortunately it went in.”

Alisson said it was the performance of his life.

“We had to be ready to suffer,” he said. “We worked hard. We gave away so many chances.

“And then at the end Harvey coming in and scoring the goal. It’s unbelievable. A great story. A great night for us.”
