#5 Jürgen Klopp

Managers play a very big role in not only the on-field performance but also the off-field conduct. Klopp is the master at just that. He, as mentioned above, has almost single-handedly changed the whole identity of the team.
He has not only instilled confidence in the players but also fans. He excels when the stakes are high and his record vs the top 6 over last two seasons is a testament to this. Under Klopp, Liverpool have played over 20 games vs top 6 rivals and have only lost 3 times.
Klopp is one of the few top-flight managers to have a better head to head record vs Pep Guardiola. Klopp also betters Mourinho who has only won once vs Klopp in 8 games. He is also yet to lose to Conte in 3 meetings with 2 draws and 1 one win for the German. Finally, Klopp also has a better record vs Pochettino with 2 wins as compared to Argentinian's 1.
If Liverpool get to the next round, they would not mind playing a fellow English team. What is surprising is that Klopp also holds the edge over Jupp Heynckes with 5 wins to his 4. So it is clear that Klopp has a lot of tricks up his sleeve and can adjust according to different styles of the managers.
Liverpool are a side which quite a few teams would like to avoid. Thanks to Klopp, they are ready to become the force they once were.
It is a long road for Liverpool but nothing significant is achieved without hard work and persistence and the 5-time European Champions are back to reclaim their beloved Champions League.
