The Brazil international became only the seventh player in the club’s history to hit the landmark, doing so in just 229 appearances.
"I'm very glad that he's my goalkeeper and we have been very successful," Virgil van Dijk remarked after the game in tribute to his teammate, echoing the sentiments of everyone of a Liverpool persuasion.
To mark Alisson’s achievement, we take a look at 10 of his most important clean sheets for Jürgen Klopp’s side from his century so far...
Clean sheet No.1: Liverpool 4-0 West Ham United - Anfield, Premier League, August 12, 2018
Typically, Alisson got his Liverpool career up and running with a shutout on his debut following his summer transfer from AS Roma.
The stopper – wearing No.13 – admittedly didn’t have a great deal to do as the Reds got the 2018-19 season started with a resounding win over West Ham at Anfield, with the visitors registering only two shots on target that afternoon.
Clean sheet No.12: Liverpool 1-0 Napoli - Anfield, Champions League group stage, December 11, 2018
Liverpool’s Champions League campaign of 2018-19 will never be forgotten – there’s a bit more of it featured on this list further down... – and Alisson’s role in the success cannot be understated.
On this particular occasion, the Reds needed to defeat Napoli 1-0 or by two clear goals to secure qualification from their group.
Mohamed Salah had put them into the lead with a trademark slalom effort; however, in the second minute of stoppage-time, the visitors forced an opening when a ball into the box flicked off the head of Fabinho and landed for Arkadiusz Milik yards out.
With our hopes of progressing hinging on this moment, Alisson produced a stunning sprawling save to avert the danger and send us into the last 16.
"If I knew Alisson was this good I would have paid double," said his manager afterwards.
Clean sheet No.25: Liverpool 4-0 Barcelona - Anfield, Champions League semi-final, second leg, May 7, 2019
Another game from our Champions League run of 2019 and although this particular night will go down in history for a comeback not even the most optimistic of fans could have dreamt of – and the small matter of a corner taken quickly – Alisson was just as influential on the outcome.
Indeed, our goalie needed to make a string of saves to keep out Barcelona, including efforts from Lionel Messi and a one-on-one with Jordi Alba, and deny the visitors the away goal that would have taken them to the Madrid final.
"It's an incredible feeling indeed, wow what a game and what an effort," Alisson said after the game amid the raw emotion inside the stadium.
Clean sheet No.27: Liverpool 2-0 Tottenham Hotspur - Estadio Metropolitano, Champions League final, June 1, 2019
And so Liverpool would go on to lift their sixth European Cup by beating Tottenham in the Champions League final in Madrid.
Salah’s early penalty and Divock Origi’s late game-clincher came either side of eight saves from Alisson at Estadio Metropolitano – the most made in the tournament’s showpiece game since 2004.
His efforts earned him a huge hug from his manager in the dressing room afterwards, while Andy Robertson put it simply: "He’s the man, isn’t he?"
"We celebrate now!" Ali himself declared as Liverpool returned home to incredible scenes across the city, with the trophy joining them.
Clean sheet No.31: Liverpool 1-0 Flamengo - Khalifa International Stadium, FIFA Club World Cup final, December 21, 2019
Liverpool had never won the FIFA Club World Cup until they defeated Flamengo in the 2019 edition in Qatar.
Roberto Firmino secured the trophy with an extra-time winner, but Alisson was excellent throughout – his best moment coming via a 58th-minute, one-handed save from Gabriel Barbosa with the scoreline still at 0-0.
Another final, another assured Alisson performance.
Clean sheet No.36: Liverpool 2-0 Manchester United - Anfield, Premier League, January 19, 2020
‘…and now you’re gonna believe us…’
For many, this was the game that cemented the belief Liverpool were firmly on course to ending their wait for the league title – and one of the most iconic images of the championship-winning campaign came in this game via our goalkeeper.
With the score at 1-0 to the Reds, but United applying pressure in search of an equaliser, Alisson claimed a ball into his area before spotting Salah ahead of him. He picked out his teammate with a precise kick that allowed the Egyptian to run beyond Daniel James and finish low at the Kop end to put the result beyond doubt.
Incredibly, the first player on scene to celebrate the goal with Salah was Alisson, who raced the length of the pitch as Anfield erupted into bedlam.
Clean sheet No.43: Chelsea 0-2 Liverpool - Stamford Bridge, Premier League, September 20, 2020
Liverpool marked their Premier League first away game of the 2020-21 season with victory over Chelsea at Stamford Bridge, a match in which Alisson notched another milestone.
The stopper produced his first penalty save for the club by keeping out Jorginho’s effort on 75 minutes and ensuring the two-goal advantage established by Sadio Mane’s brace remained intact.
It wouldn’t be the last time he’d frustrate the Blues from 12 yards…
Clean sheet No.84: Liverpool 0-0 Chelsea - Wembley, FA Cup final, May 14, 2022
Alisson had a decisive hand in ensuring the Emirates FA Cup was added to Liverpool’s trophy cabinet once again in 2022.
After an absorbing, but ultimately goalless, 120 minutes of action against Chelsea at Wembley, the tie went to penalties.
And our custodian capped an excellent display by saving from Mason Mount in the shootout to enable Kostas Tsimikas to sweep in the winning kick.
Jordan Henderson said of our No.1 afterwards: "He’s unbelievable. Incredible. In games – everything; build-up, shot-stopping, his all-round personality in the dressing room. As he is as a man – incredible."
We certainly concur.
Clean sheet No.88: Liverpool 1-0 Manchester City - Anfield, Premier League, October 16, 2022
It’s incredible to think a goalkeeper can offer an attacking threat, but that’s exactly what Alisson gives Liverpool.
Indeed, the 30-year-old claimed yet another assist to help the Reds edge out Manchester City at Anfield back in October.
It was almost a cut-and-paste job from his tee-up for Salah against United – this time the No.11 sprang clear of Joao Cancelo and finished smartly beyond Ederson after collecting his goalkeeper’s long pass.
Alisson is credited with three assists for the club to date – all provided to Salah – and one goal, a famous late winner against West Bromwich Albion in May 2021.
Clean sheet No.100: Liverpool 1-0 Brentford - Anfield, Premier League, May 6, 2023
And so Alisson reached a century of clean sheets for Liverpool with a typically commanding display against Brentford on Saturday, helping to extend our winning run to six matches.
The visitors – described by Jürgen Klopp as ‘the best set-piece team I ever played’ – caused concern for the hosts with a number of balls into the area, but our ‘keeper repelled them with a series of punches and catches, as well as a smart, improvised one-handed save to prevent Bryan Mbeumo from going through on his goal in the second half.
Reflecting on his achievement, Alisson told us: "I don't know how much it means, 100, I hope I'm going to reach 200, 300, as many as possible.
"But this is not only a number of myself, it's from all the boys, from all the staff, goalkeeping coach department, everybody. We work together with a common goal and a clean sheet is a common goal of ourselves. Clean sheets can put us in a closer situation to win games."
Here's to the next 100, Ali.
