The Klopp era began on October 8, 2015 and his first game took place nine days later at White Hart Lane against Mauricio Pochettino's Tottenham.
But who took to the field for Liverpool in London that day and where are they now? Here we take a look back at Klopp's first starting line-up and some of the numbers from his reign at Anfield...
Mignolet joined Liverpool from Sunderland in 2013 and remained the club's number No 1 goalkeeper throughout Klopp's first two seasons at the club. In January 2016 he signed a new five-year deal with the club but the following summer he faced competition from Loris Karius, who Klopp brought in from Mainz.
The Belgian initially held off the challenge from Karius, who broke his hand in pre-season, but Klopp eventually announced the German goalkeeper as his first choice with Mignolet consigned to the bench. It was thought the 31-year-old would drop even further down the pecking order with the arrival of Alisson Becker from Roma, but the decision to loan Karius to Besiktas saw Mignolet stay for another season before moving back to Belgium with Club Brugge this August.
Clyne had only just arrived at Anfield himself when Klopp was appointed but he was already an England international from his Southampton days and the right-back impressed initially for Liverpool. He remained the first-choice right-back for the rest of that season and the whole of the following campaign before suffering a back injury in the summer of 2017.
The return to fitness of Joe Gomez coupled with the emergence of Trent Alexander-Arnold meant that by the time Clyne was ready to compete for his place again the situation had changed. Last season, there was a loan spell at Bournemouth, but a cruciate ligament injury suffered in training in the summer leaves Clyne, now 28, facing another lengthy spell out.
Skrtel spent eight-and-a-half years at Anfield and made 320 appearances in all competitions for Liverpool, but just 19 of those appearances came under Klopp. Despite starting Klopp's first game in charge, he fell quickly down the pecking order following the emergence of the partnership between Dejan Lovren and Mamadou Sakho.
Kept out of the starting XI for much of the second half of the season, the defender joined Fenerbahce for £5m in the summer of 2016. After three seasons in Turkey he moved to Italy with Atalanta but following a bust-up with coach Gian Piero Gasperini he left the Italian club just 24 days after signing and returned to Turkey with Istanbul Basaksehir.
Mamadou Sakho may have had a mistake in him on his day but he was firmly a part of Klopp's first choice centre-back pairing up until failing a routine drugs test in March 2016, although he was later cleared by UEFA.
That should have settled things - but Sakho was then sent home from Liverpool's pre-season tour of the USA in July 2016 for breaking club rules.
He turned down a move away from the club that summer but in the end, he joined Crystal Palace on loan in January 2017, having failed to play a single Premier League minute for Liverpool that season, and signed permanently at Selhurst Park the following summer.
Moreno was Liverpool's first-choice left-back when Klopp arrived, but his defensive limitations had already been well documented and he found life difficult adapting to the new manager's pressing game.
James Milner was drafted in as Liverpool's stand-in the following season which saw Moreno restricted to two league starts, later finding himself further sidelined by the arrival, and success, of Andy Robertson, although he did start nine games on Liverpool's run to the Champions League final in 2017/18.
His Liverpool career finally came to an end in the summer, when he left on a free transfer and subsequently joined Villarreal.
The ever-reliable Milner is the only player to start Klopp's first game in charge of Liverpool and his most recent one - even scoring the stoppage-time winner against Leicester last time out. Now 33, he has featured in 168 matches under Klopp, coming off the bench to play his part in the team's Champions League triumph over Tottenham in June.
He has filled in as a full-back for long periods but it is as a relentless midfielder that Milner has proven most effective, typifying the spirit of Klopp's Liverpool. His contract is up at the end of the season but talks over a new deal are ongoing. Do not be too surprised if Milner is still in that Liverpool line-up on the fifth anniversary of the German's time in charge.
Perhaps, the one who got away? Signed in the summer of 2014, Can showed flashes of brilliance under Klopp - a wonder goal away at Watford sticks in the memory - and grew to become one of Liverpool's first-choice midfielders in Klopp's first two seasons at Anfield. The midfielder scored the first goal of the Klopp era, netting in Liverpool's 1-1 draw with Rubin Kazan in the Europa League.
He continued to flourish under Klopp during the 2016/17 and 2017/18 seasons, but with talks over a new contract stalling, his future at the club was thrown into doubt. By March 2018, Can had scored six goals but an injury threatened to ruin his season. He did return to feature in Liverpool's Champions League defeat to Real Madrid, but it proved to be last appearance for the club before a move to Juventus. The 25-year-old ended his first season as a Serie A title winner, but with competition for places fierce in Turin he found himself left out of Juve's Champions League squad this season.
Lucas Leiva was already old hat by the time Klopp arrived, having joined Liverpool back in 2007. He was handed the captain's armband against Crystal Palace a month after the new manager joined, but the arrival of Georginio Wijnaldum the following summer saw him pushed down the pecking order.
Only making 12 starts in 2016/17 proved too much for the Brazilian to deal with, and he was sold to Lazio for £5m.
Lallana flourished with the attacking licence given by Klopp, picking up six assists during the German's first season at the helm, and another seven the year after, when he also netted eight league goals.
Injuries have devastated his club career ever since, starting only six league games in the intervening two-and-a-bit years. Lallana did come on from the bench on Saturday against Leicester as he continues his comeback from another setback, but poor physical health may have stolen what could have been a bright few years under Klopp from the former Southampton man.
A key figure at Anfield when Klopp arrived, Coutinho remained one of the first names on the team sheet for the remainder of the German's first season with Liverpool. He went on to score 12 goals in all competitions during the 2015/16 season and continued his excellent form under Klopp, producing thirteen goals in 31 games in the following campaign.
Coutinho's importance at Liverpool was recognised when he signed a new long-term deal with the club in January 2017, but Barcelona eventually came calling and just a year later he was on his way to the Nou Camp in a staggering deal worth £142m. However, the Brazilian failed to make the same kind of impact he made at Anfield in Spain, and this summer he was sent on loan to Bayern Munich, where he has scored two goals in his eight appearances so far this season.
Chosen essentially by default with Christian Benteke and Daniel Sturridge both ruled out, Origi nearly took full advantage of his starting berth when he struck the bar with an early header on Klopp's debut.
Since then, Origi has proven a useful squad player for Klopp, scoring seven times from 14 league starts the following season before spending 2017/18 on loan at Wolfsburg. But if that suggested he might be on his way out of Anfield, his performances last season had him back in the door.
A last-minute winner in the Merseyside derby, another late winner at Newcastle and goals in the Champions League semi-final and final earned him a new long-term contract at Anfield earlier this year.
Joe Allen - A favourite of departing boss Brendan Rodgers, Allen found life tough going in the all-action approach Klopp adopted in the early days of his Liverpool career. A number of hamstring injuries did little to help him impress the new manager, and he moved to Stoke for £13m the following summer.
Jordon Ibe - Ibe enjoyed what looked like it might be a breakthrough season in some of Klopp's first year in charge at Anfield, but it proved a false dawn as he was deemed surplus to requirements and shipped out to Bournemouth for a healthy £15m. Having made his first-team bow the year before, Ibe started 10 of the 30 league games Klopp presided over in his first campaign, but managed just two assists and one goal from 27 appearances - and his time was up.
