2. Jurgen Klopp

Teams managed this decade - Borussia Dortmund, Liverpool Football Club
The man behind the popularity and innovation of "gegenpressing", Jurgen Klopp is arguably the greatest leader of men that the world of football has ever seen. A football lover to his core, the 6'4" former German international may look like a happy, smiling father figure, but behind that wide smile and the kind eyes lies one of the best footballing brains to enter the world of management.
Klopp started off this decade as the manager of German club Borussia Dortmund. He was successful in breaking the Bayern Munich hegemony of the Bundesliga as he went on to capture back-to-back first division titles with his men in black and yellow. He came up short against Bayern in the finals of the Champions League in 2013, and he left Dortmund a couple of seasons later after seven years in charge. The job which he did with the club on a minimal budget and with star players leaving is nothing short of historic.
Appointed the Liverpool manager in 2015, Klopp has transformed the Reds from a midtable team to a side which reminds one of the days of Bob Paisley and Bill Shankly, a period where the team dominated world football. Despite losing his first three finals with the club, Klopp had his sweet moment when he led his team to Champions League glory in 2019.
At the time of writing, Liverpool are 10 points ahead of their closest rivals in the Premier League table with half the season to go, and it looks likely that their 30-year-old league trophy drought will end come May 2020. Klopp believes in the ideology of pressing, wherein he makes use of the spaces which players can operate it more than the possession stats. Gegenpressing, a tactic which the former Mainz manager made famous, is a style of play wherein which the team, after losing possession of the ball, immediately attempts to win back possession, rather than falling back to regroup.
Klopp has stated that a well-executed counter-pressing system can be more effective than any playmaker when it comes to creating chances. The Liverpool coach has reached 4 European finals this decade and is the winner of several major trophies. However, his most important trait is perhaps his charisma and his ability to motivate his men, which is second to none. Not only is Jurgen Klopp a legendary manager, but he is also a model leader who inspires his team to glory.
