#3 Liverpool vs Manchester City, 4-3, Premier League, 2017-18
Klopp's Liverpool and Pep Guardiola's Manchester City, two juggernauts of modern day football, met at their respective peaks in January 2018.
By then, Manchester City had hit extraordinary levels, having accumulated 106 goals and 100 points in the 2017-18 season.
The January fixture saw Liverpool push them to the edge and beyond as Alex Oxlade-Chamberlain and Leroy Sane scored in the first half. It was then the trio of Mohamed Salah, Sadio Mane and Roberto Firmino that shocked Manchester City, scoring within 10 minutes of each other.
Pep Guardiola’s team came close as Bernardo Silva and Ilkay Gundogan pulled a couple of goals back. But Klopp's Liverpool eventually defeated City to stop a ruthless winning streak and strike fear into blue hearts. The Reds proved they had the mettle for a title challenge and while it didn't happen that season, it ultimately materialized in the 2019-20 campaign.
#2 Borussia Dortmund vs Real Madrid, 4-1, Champions League, 2012-13
Entering the semi-finals after a last-gasp victory, Klopp's Dortmund were firm underdogs against a mighty Real Madrid team. Los Blancos were then managed by Jose Mourinho and boasted Cristiano Ronaldo, Mesut Ozil and Sergio Ramos in their ranks.
The first leg at Signal Iduna Park defied expectations, as an inspired Robert Lewandowski announced his arrival on the largest stage. He scored four goals against one of the best teams in world football and the record-breaking La Liga champion. Undoubtedly, the performance quickly became the stuff of legend.
Klopp's hard-running, gegenpressing style meant Dortmund had the capacity to capitalize on errors, resulting in one of the greatest results in the club's history. Dortmund marched to the finals of the Champions League despite a 2-0 loss in the reverse fixture. In the summit clash, Klopp's side were narrowly beaten by a skilled Bayern Munich who secured a treble.
#1 Liverpool vs Barcelona, 4-0, Champions League, 2018-19
One of the most remarkable football games played in the history of European competition, the unthinkable comeback against Barcelona still defies rational explanation.
Liverpool entered the home game of this Champions League semi-final with a three-goal defeat, without star players Mohamed Salah and Roberto Firmino. But the impossible was challenged head first with a buoyant Anfield cheering and energizing their heroes towards the goal.
With Jurgen Klopp as cheerleader in chief, Liverpool stormed ahead displaying improbable mental strength, technical ability and quick thinking. Divock Origi's clever goal from a quick Trent Alexander-Arnold corner instantly became part of Liverpool folklore.
The nature of the victory, displaying self-belief and character, almost single-handedly guaranteed Liverpool would lift the Champions League that year. Klopp's side ultimately did as well, beating a toothless Tottenham Hotspur 2-0 in the summit clash.
