Mohamed Salah was the hero for Liverpool on Tuesday night as the Egyptian's goal sealed a 1-0 victory over Napoli and a place in the Champions League last 16.
Victory for the Reds at Anfield meant they leapfrogged their Italian opponents into second, while Paris Saint-Germain finished top of Group C.
Liverpool are once again looking very strong in Europe and one big reason for that is Alisson, who has been phenomenal since joining in the summer for £65m.
He made another huge save against Napoli to deny Arkadiusz Milik in stoppage time, with the Brazil goalkeeper blocking a shot from point-black range.
Had Milik equalised for Napoli they would have gone through to the last 16, not Liverpool, so it's no exaggeration that Alisson's save was one of his most important yet.
Jurgen Klopp couldn't help but rave about his No.1 after the game and described the last-minute block as "incredible" and "unbelievable".
"It was not only one save," said Klopp, "he had a lot of things to do tonight. How cool and calm he was with the ball helps us a lot in our build-up situations.
"When he comes out for crosses he is outstanding. And that save was just incredible. He did it... incredible, unbelievable."
Alisson's positioning and reflexes have saved Liverpool on numerous this season, while his composure and distribution has allowed them to play out from the back.
David Preece, who is a former goalkeeper-turned-journalist, was in awe of Alisson's performance and spotted a moment during the second half that he thinks was overlooked.
In the video below, Alisson demonstrates his passing accuracy by splitting Napoli's forwards with a risky yet pin-point pass straight to the feet of James Milner in the middle of the park.
Rival fans will argue that Alisson's pass was a simple one, but there aren't many goalkeepers in the world with the confidence or ability to play it and that's what makes the Brazilian so special.
He's added a whole new dimension to Liverpool's defence and style of play, which is exactly why Klopp paid so much to bring him to Merseyside.
