Klopp's side finished second in the 2018–19 Premier League, registering 97 points; the then third-highest total in the history of the English top division, and the most by a team without winning the title.

[12][15] As a young boy, Klopp aspired to become a doctor, but he did not believe he "was ever smart enough for a medical career," saying "when they were handing out our A-Level certificates, my headmaster said to me, 'I hope it works out with football, otherwise it's not looking too good for you.

"[23] As a player, Klopp closely followed his manager's methods on the training field as well as making weekly trips to Cologne to study under Erich Rutemöller to obtain his Football Coaching Licence.

[28] In his first full season in charge in 2001–02, Klopp guided Mainz to finish 4th in the league as he implemented his favoured pressing and counter-pressing tactics, narrowly missing promotion.

Despite having interest from German champions Bayern Munich,[15] Klopp eventually signed a two-year contract at the club, which had finished in a disappointing 13th place under previous manager Thomas Doll.

[15][39] After losing 2–0 to Bayer Leverkusen on the opening day of the 2010–11 Bundesliga, Klopp's Dortmund side won fourteen of their next fifteen matches to secure the top spot in the league for Christmas.

[70] On 4 January 2014, it was announced that Dortmund striker Robert Lewandowski signed a pre-contract agreement to join Bayern Munich at the end of the season, becoming the second key player after Götze to leave the club within a year.

[83] The mathematical model turned out to be that of Cambridge physicist Ian Graham, which was used to select the manager, Klopp, and players essential for Liverpool to win the Champions League.

[94] On 14 April, Liverpool fought back from a 3–1 second half deficit in the second leg of their quarter-final match against his former club Dortmund to win 4–3, advancing to the semi-finals 5–4 on aggregate.

[111] In the summer transfer window, Klopp made a number of high-profile signings including midfielders Naby Keïta and Fabinho,[112][113] forward Xherdan Shaqiri[114] and goalkeeper Alisson.

Klopp's side finished second in their group by virtue of goals scored to qualify for the knockout phase,[127] before drawing German champions Bayern Munich in the round of 16.

[134] In the second leg, Klopp's side overturned the deficit with a 4–0 win, advancing to the final 4–3 on aggregate, despite Mohamed Salah and Roberto Firmino being absent with injuries, in what was described as one of the greatest comebacks in Champions League history.

At the awards ceremony, Klopp revealed that he had signed up to the Common Goal movement, donating 1% of his salary to a charity which funds organisations around the world using football to tackle social issues.

[147] Following a victory against Red Bull Salzburg on 10 December that saw Liverpool top their Champions League group,[148] Klopp signed a contract extension that will keep him at the club until 2024.

[164][165] Beginning the season prior, Liverpool also enjoyed a 44 match unbeaten run in the league – the second-longest streak in top-flight history – ended by Watford on 29 February.

[170] After winning the opening three league games of the 2020–21 season against Leeds United, Chelsea and Arsenal, on 4 October 2020, Klopp's side lost 7–2 away to Aston Villa.

[181] On 1 December, Klopp led Liverpool to a 4–1 away win against Everton in the Premier League as the club became the first team in English top-flight history to score at least two goals in 18 successive games in all competitions.

[202] It was suggested that reasons for this failure to qualify for the Champions League included the declining form of key members of the team[203][204][205][206][207] and the vast amount of injuries suffered by Liverpool players.

Klopp and his coaching team wore a red jumper with 'I'll Never Walk Alone Again' on the rear and 'Thank You Luv' on the front – a phrase he closely associates with the city of Liverpool.

[223] The farewell celebrations were concluded with an event held M&S Bank Arena called "An evening with Jurgen Klopp", hosted by comedian John Bishop on 28 May 2024.

[231] Despite Klopp's pressing tactics resulting in a high attacking output, his Liverpool side was criticised at times for its inability to control games and tendency to concede goals as well as score them.

[233] However, Klopp developed his tactics to incorporate more possession based football and more defensive and midfield organisation,[234] as well as overseeing the transfers of Alisson Becker, Virgil Van Dijk, Naby Keïta and Fabinho ahead of the 2018–19 season which saw Liverpool achieve their best league start in the club's history, and equal the all-time record for the fewest goals conceded at the mid-point of a top-flight season, conceding just 7 goals and keeping 12 clean sheets.

[236] In his first two full seasons at Liverpool, Klopp almost exclusively employed a 4–3–3 formation, using a front three of wingers Mohamed Salah and Sadio Mané surrounding false-9 Roberto Firmino, supported by Philippe Coutinho in midfield.

[238] Following Coutinho's departure in January 2018, the remaining front three increased their attacking output and continued to create chances as Salah won the Premier League Golden Boot in 2018,[239] before sharing the award with his team-mate, Mané, in 2019.

[252] Klopp was described by Jonathan Wilson of The Guardian as "a hugely charismatic figure who inspires players with his personality",[253] while Vincent Hogan of the Irish Independent writes, "Not since Bill Shankly have Liverpool had a manager of such charisma".

[255] He received criticism in 2018 for taking things 'too far' when running on to the pitch to embrace Alisson Becker to celebrate an added time winner in the Merseyside derby.

[273] On 1 October 2024, Klopp received the Federal Order of Merit from President Frank-Walter Steinmeier at Bellevue Palace in Berlin, for his contribution to democracy and his impact on the football world and more.

He was previously wedded to Sabine, and they have a son, Marc (born 1988),[275][276] who has played for a number of German clubs including FSV Frankfurt under-19s, KSV Klein-Karben, SV Darmstadt 98, Borussia Dortmund II and the Kreisliga side VfL Kemminghausen 1925.

[302] According to Horizont, trade magazine for the German advertising industry, and the business weekly Wirtschaftswoche, Klopp's role as "brand ambassador" for Opel successfully helped the struggling carmaker to increase sales.

"[310] After Liverpool's title win in 2020, the Brewery also produced a special limited edition series of cans featuring Klopp's face and autograph, which sold out quickly online.
