In just four-and-a-half years Jurgen Klopp has completely overhauled Liverpool.
The German has changed the culture at Anfield, secured a Champions League triumph - and also overseen a reconstruction of the squad.
No fewer than 34 players have joined the club since the appointment of Klopp in 2015, but how does each of them rate?
Adrian - B-
Adrian started well this season when unexpectedly having to fill in for Alisson - helping the Reds secure a Super Cup. Those penalty shootout heroics will always be remembered by Reds fans. More recently, however, the Spaniard made costly mistakes against Atletico Madrid in the Champions League.
Jack Bearne - C
Signed from Notts County in 2017, Jack Bearne only turned 18 last September and so cannot be judged as a Liverpool player until he has started his senior career. Nonetheless, Bearne is highly rated as a number 10, centre forward or winger. His versatility could stand him in good stead going forward.
Alisson Becker - A+
Having lost a Champions League final on the basis of a poor goalkeeping performance, Liverpool went out and grabbed the best shot-stopper they could find in the summer of 2018. Alisson Becker is now considered one of the best goalkeepers in world football and is well on his way to becoming a Liverpool legend.
Isaac Christie-Davies - C
Isaac Christie-Davies made the switch from Chelsea to Liverpool in 2018, but has yet to make a senior appearance for the Reds. Instead, the talented midfielder is out on loan with Cercle Brugge. Now 22 years old, it's possible that he will start looking for first team football elsewhere before too long.
Bobby Duncan - D
Signed from Manchester City in 2018, Bobby Duncan quickly earned himself a reputation as one of Liverpool's best hopes for the future. But Duncan controversially swapped Merseyside for Fiorentina last summer, with an incendiary social media post from then agent Saif Rubie causing a stir. In January, reports emerged of Duncan's new club reportedly pleading to FIFA for the chance to offload the former Liverpool forward.
Harvey Elliott - B-
Already the youngest player to have ever played in the Premier League, Harvey Elliott is arguably Liverpool's greatest hope for the future. The 16-year-old has made a couple of first-team appearances this season and has impressed at almost every opportunity.
Fabinho - A
It took a little while for Fabinho to find his way as a Liverpool player following the £39million switch to Anfield from Monaco in the summer of 2018, but the Brazilian is now an integral part of Klopp's side. That position at the base of the midfield looks to be his for many years to come.
Tony Gallacher - C-
The Scottish left back made the £200,000 move from Falkirk to Liverpool in 2018, but has struggled to make his mark on Merseyside. Tony Gallacher will be 21 in July and must start thinking about where he can kick start his career. Liverpool already have one Scottish left back.
Kamil Grabara - C
Given Kamil Grabara's pedigree as a Polish youth international, and Liverpool's goalkeeping troubles in recent years, it's somewhat surprising that the 21-year-old hasn't made a senior appearance for the Reds. On loan at Huddersfield Town, Grabara is one worth persevering with for a little longer.
Joe Hardy - C
Not much was made of Joe Hardy's arrival from Brentford in the January transfer window, with the addition of Minamino attracting most of the headlines, but the former Man City youngster could give Liverpool some depth in the attacking positions.
Ki-Jana Hoever - C+
Along with the signing of Sepp van den Berg, Liverpool's addition of Ki-Jana Hoever last summer was made with a focus on the future. Chelsea, Man City and Man Utd were all thought to be interested in the Dutch defender, but Anfield was where he believed he would progress most and the young Dutchman has started to flourish having already played for the first-team a number of times.
Loris Karius - D
His mistakes cost Liverpool dearly in the 2018 Champions League final and that, unfortunately for the German, is how Loris Karius' career for the club will be remembered. Currently on loan at Besiktas, it's possible Karius could return as a second choice option, but he will never be the Reds' number one again.
Naby Keita - B-
At the time, Naby Keita was seen as the perfect Liverpool midfielder. Energetic, good with the ball at his feet and positionally aware, the £48 million signing from RB Leipzig was meant to take Klopp's midfield to the next level. That hasn't quite materialised yet.
Billy Koumetio - C
Billy Koumetio is another promising young centre back on Liverpool's books. The 17-year-old was promoted to first team training last October and all signs point to Klopp rating the defender highly. It might not be long before he makes a breakthrough.
Marko Grujic - C-
Highly rated by many as a full Serbian international, Mark Grujic has never managed to fulfil his potential as a Liverpool player. Currently on loan at Hertha Berlin, it seems unlikely that the 23-year-old will ever make the grade under Klopp, although he could still have a good career elsewhere.
Vitezslav Jaros - C
Had Vitezslav Jaros not suffered an injury in pre-season last summer there's a chance the Czech goalkeeper might have been given an opportunity as Alisson Becker's deputy. The 18-year-old will have to continue to bide his time for a chance between the Anfield posts, though.
Ragnar Klavan - C+
Maligned for a number of mistakes made, Ragnar Klavan embodied Liverpool's great need to improve defensively up until the arrival of Van Dijk. However, the German was never as bad as many believed and was a favourite for Klopp for a couple seasons.
Yasser Larouci - C+
The 19-year-old Algerian is one of Liverpool's next crop of young superstars, catching the eye in the Reds' FA Cup victory over Everton this season. Yasser Larouci is currently Klopp's third choice left back behind Robertson and James Milner, but has time to move up the pecking order.
Andy Lonergan - N/A
The veteran goalkeeper arrived at Anfield to ease Liverpool's goalkeeping shortage at the start of the season, but has so far failed to make an appearance for the Reds. His short-term contract means he will almost certainly leave the club at the end of the season.
Sadio Mane - A+
Sadio Mane showed promise at Southampton, but few could have envisaged how his development would accelerate quite so dramatically upon signing for Liverpool. Mane has now scored 77 times for the Reds and is arguably their most dependable forward.
Alex Manninger - N/A
It's easy to forget that Alex Manninger, formerly of Arsenal and Juventus, signed for Klopp's Liverpool, signing a short term contract to join the Anfield club for the 2016/17 season. However, the Austrian failed to make a single appearance and retired soon after.
Joel Matip - B
Joel Matip arrived at Anfield with very little fanfare, joining Liverpool as a free agent in the summer of 2016. The Cameroonian international has his flaws, but has proved himself as an effective option at centre back for Klopp. He has got better with almost every season he has played.
Liam Millar - C-
The hope was that Liam Millar's career would be fast tracked by a loan to Kilmarnock for this season. However, the Canadian's stint in Scotland was cut short and now faces a fight to prove he has a future at Liverpool.
Takumi Minamino - B-
Signed only in January, it's too early to make any sort of conclusive judgement on Takumi Minamino's Liverpool career. However, the £8 million fee paid for the Japanese international was well below market value and the early signs have been positive.
Alex Oxlade-Chamberlain - B+
The £35 million signing of Alex Oxlade-Chamberlain from Arsenal in 2017 looked to be something of a gamble for Liverpool. The 26-year-old's injury record hasn't improved much, but Klopp has turned him into an extremely effective central midfield force.
Nat Phillips - C-
The 22-year-old centre back has spent much of the last two seasons on loan at Stuttgart, but has yet to show that he has the potential to truly make it as a Liverpool player. It seems likely that Nat Phillips will be moved on at some point soon, but could still find a club at a good level.
Andy Robertson - A+
Signed for just £8 million from Hull City, Andy Robertson now stands as one of the best bargains of the Premier League era. The Scot is one of the best full backs in the European game and is the perfect supply line to the likes of Firmino, Mane and Salah.
Mohamed Salah - A+
Few expected Mohamed Salah to flourish in the way he has since signing from Roma for around £34 million in the summer of 2017, but the Egyptian has gone to become the face of Klopp's Liverpool, breaking record after record for the Reds. If Salah is not already a Liverpool legend, he will be soon.
Xherdan Shaqiri - C+
At first Xherdan Shaqiri's signing from Stoke City for just £13 million looked to be a shrewd one. The Swiss made a good impression in his first season as a Liverpool player, giving Klopp some much-needed squad depth. Since then, though, Shaqiri has fallen out of favour and could be moved on soon.
Dominic Solanke - C
Liverpool's signing of Dominic Solanke from Chelsea in 2017 looked to be quite the coup. The striker was seen as one of England's brightest hopes for the future, but was sold to Bournemouth 18 months later. The biggest benefit of Solanke's signing was that Liverpool made a healthy profit on him.
Virgil van Dijk - A+
His £75 million signing in the January transfer window of 2018 will go down as a turning point in Liverpool's modern history. Indeed, Virgil van Dijk's impact was instant and is now seen as the best centre back in Europe, and one of the best of all-time in the Premier League.
Sepp Van Den Berg - C
Last year's £1.3 million signing of Sepp Van Den Berg was made with one eye on the future. The 17-year-old centre back had the option to sign for Bayern Munich instead, but decided Liverpool was the place for him to develop.
Georginio Wijnaldum - A
It's fair to say that Georginio Wijnaldum has changed as a player since his move to Liverpool. At Newcastle United, he was a goalscoring attacking force, while Klopp has effectively deployed him as more of a midfield anchor. Wijnaldum has still kept his propensity for goals on the biggest of occasions.
Ben Winterbottom - C
Viewed as one of the most promising young goalkeepers in the country, Liverpool's signing of Ben Winterbottom from Blackburn Rovers last year was an investment in the future. Of course, displacing Alisson as the Reds' first choice keeper might prove tough, but it's possible that he could be a second-choice option soon.
