#3 Andy Robertson (€9 million)
Andy Robertson is the true definition of a proper Jurgen Klopp bargain signing. Liverpool’s left-back conundrums have been well documented during Brendan Rodgers’ reign and Jurgen Klopp’s first couple of seasons at Anfield. Robertson’s consistent displays have made him one of the first names on the team sheet.
The Scottish captain was bought from Hull City for just €9 million. In late 2019, Robertson’s market value touched €80 million, which goes to show what a sensational signing he has been for Jurgen Klopp.
The left-back has made 191 appearances for Liverpool, winning the Premier League and UEFA Champions League along the way.
Alongside fellow full-back Trent Alexander-Arnold, Robertson has been a creative force for Jurgen Klopp's Liverpool. His attacking exploits have landed him 41 assists so far.
A fruitful 2019 earned him a spot in UEFA’s Team of the Year as Europe’s best left-back. He remains one of the best players in his position, which is a testament to his consistency.
#2 Mats Hummels (€4.2 million)
Mats Hummels ranks among the best centre-backs of 2010s. During his prime, there weren’t many strikers who could outthink the German. Positionally adept, Hummels used his footballing mind to always stay a step ahead of the opposition forwards. Despite lacking pace, he was right up there with the most potent centre-backs during his prime.
Hummels played on 242 occasions for Jurgen Klopp at Dortmund in a stint that was sandwiched between his time at Bayern Munich. The German international returned to Dortmund in 2019 and is a regular feature in the team’s line-up under Marco Rose.
Hummels cost a mere €4.2 million when he was first signed for the club back in 2008. He won six trophies during his initial stint at Signal Iduna Park, including a couple of Bundesliga titles. He also played a key hand in Germany’s 2014 FIFA World Cup triumph.
#1 Robert Lewandowski (€4.75 million)
Just like the award for “Best Striker” at last night’s Ballon d’Or award ceremony, the top spot on this list comes as a consolation for the Polish striker. He probably deserved to pip Lionel Messi to the 2021 Ballon d’Or award.
Lewandowski has been a top-notch striker for the majority of the last decade, and he only seems to be getting better with time.
The former Borussia Dortmund marksman was purchased by Jurgen Klopp for €4.75 million. He scored 102 goals and registered 42 assists during his 186 matches under Jurgen Klopp. Lewandowski left Signal Iduna Park in 2014 on a free transfer and has taken his poaching ability to a whole new level.
Lewandowski’s skill set as an out-and-out number 9 cannot be matched by any player in Europe over the last few seasons. He broke Gerd Muller’s Bundesliga record for most goals in a single campaign last season and has started the current campaign with a bang.
Lewandowski has arguably been the best player over the previous two calendar years. And to think Klopp introduced him to the world following a deal that cost under €5 million is unbelievable.
